The Daily Telegraph said the woman received a six-figure sum after the alleged relationship with Mr Infantino, the embattled FIFA president who is facing calls to quit over his plan to sell off a stake of the World Cup to private investors.
UEFA paid for the woman's MBA degree after she left the organisation, the paper reported.
In a statement to Sky News, UEFA said a "departure payment" was made to a woman as well as "the payment of fees for an MBA course at a local business school".
"The payment was in line with the regulations that existed for departing staff at the time," a spokesperson added.
"Such regulations have been tightened since 2016 and the current staff regulations - which apply to all UEFA employees at whatever level - reflect those found in a modern, high-profile organisation."
A FIFA spokesman told Sky News that Mr Infantino "strongly denies these allegations, and they are categorically untrue".
They added: "Any insinuation of inappropriate conduct or violation of statutes or regulations is defamatory."
Mr Infantino worked at UEFA from 2000 until leaving in 2016, when he took up his current role at FIFA.
In response to the claim that senior figures at UEFA had concerns over Mr Infantino's conduct, the FIFA spokesman said: "No employee at UEFA and FIFA has ever raised a complaint regarding Mr Infantino's behaviour because there never was an incident where he was involved.
"All company actions related to employees, including any departure and severance packages, have always been approved by the appropriate directors in accordance with all applicable regulations."

FIFA's controversial sell-off plans triggered a row between the sport's governing bodies that led to Mr Infantino eventually abandoning the proposal and apologising.
Despite this, UEFA insisted on Thursday that it was still prepared to boycott any future World Cups as it had lost confidence in Mr Infantino.
Even as the widespread calls for him to step down grow, he is showing no signs of quitting.
The English FA sent a letter to FIFA withdrawing its support for Infantino's re-election as president, Sky News reported on Thursday - and on Friday, Norway's football federation asked him to "resign now".
UEFA told Sky News that the "conditions have not been met" to lift its World Cup boycott, and there is still a lack of confidence in Mr Infantino.
Meanwhile, Mexico, Argentina, Qatar, Egypt and Morocco have thrown their support behind Mr Infantino.
The yellow heat health alerts are in place from 9am on Saturday and to 9pm on Tuesday, covering most of England, apart from the North East and North West.
The Met Office said temperatures will climb through the weekend, and will hit a high of 36C in parts of East Anglia and South East England by Thursday.
The UK has already seen two record-breaking heatwaves, in May and June, which have been linked to more than 2,700 excess deaths. Two further heatwaves in July have fuelled drought and wildfires.
There have been 33 days so far this year when temperatures have exceeded 30C somewhere in the UK and the record of 34 days - set in 1995 - will likely be broken next week.
Forecasters say the weekend will see a national divide in the weather, with Scotland and Northern Ireland likely to see spells of heavy rain, while England and Wales will remain largely dry, sunny and increasingly hot.
Temperatures could reach 30C (86F) on Saturday, before climbing into the low 30s in southern England on Sunday.
Highs of up to 30C are possible across parts of England and Wales on Tuesday, increasing to 32C to 34C (90F to 93F) on Wednesday, with the highest temperatures currently expected on Thursday.
'Several more areas' could move into drought
The forecast comes as the Environment Agency confirmed that last week was the seventh consecutive week in which England received less than 10mm of rainfall.
The agency suggested "several areas" could move towards or into drought next week, in addition to the half of England already in drought.
The Environment Agency is already planning to introduce formal restrictions on the amount of water that can be removed from natural sources in parts of East Anglia to protect exceptionally low river flows.
Reservoir storage in England has also dropped to 69%, down from 72% a week ago and nearly 12% below the long-term average for this time of year, the agency said on Friday.
Storage stood at 85% at the end of June, which was the average for that point in the year, but has fallen steadily in the past few weeks.
Five reservoirs are now classed as having "exceptionally low" levels: Blagdon in Somerset (54% full); Clywedog in Powys, which provides water for central and North West England (62%); the Dove group of reservoirs in Derbyshire (74%); Hanningfield in Essex (60%); and Wimbleball in Somerset (50%).
Wildfires to become 'exceptionally severe'
Last month was the driest July for England and Wales since records began in 1836, with 19 counties across England recording effectively no rainfall - 1mm or less - according to provisional figures released by the Met Office.
It comes after several wildfires have broken out in the UK this summer, with large blazes in Suffolk, on the Isle of Wight, in the Rhondda Valleys, South Wales, and the Cairngorms National Park in Scotland.

The Fire Severity Index, which evaluates how severe a wildfire could become if one were to ignite under current weather conditions, says fires are likely to become exceptionally severe - its highest ranking - on Sunday for almost all of the East and South East of England.
The Met Office data includes rainfall, temperature and humidity, but the index does not cover the chances of wildfires occurring.
Joshua Kerry, 28, has been charged with the murder of the former Conservative minister, who was found dead at her Devon home on 9 July.
In an update on Friday, it was revealed the Metropolitan Police received a report of an attempted burglary at an address in the Greater London area in April 2025.
Counter terror police have now reopened the investigation into this incident, and a staff member has been referred to the police watchdog for allegedly failing to follow up a line of inquiry.
"Enquiries were carried out by the Metropolitan Police, supported by Counter Terrorism Policing London," said Vicki Evans, senior national coordinator for counter terrorism policing.
"No arrests were made, and the investigation was subsequently closed, pending any new lines of enquiry."
Ms Evans added: "Following the reopening of the attempted burglary investigation, Counter Terrorism Policing London identified a line of enquiry which was not identified and pursued by them at the time, which may have been relevant.
"As a result, to ensure their support to the initial investigation is thoroughly reviewed, Counter Terrorism Policing London made a mandatory conduct referral to the Independent Office for Police Conduct (IOPC).
"We will engage fully and comprehensively with the IOPC on this matter.
"The victims and families in both investigations have been updated today, and we continue to support them."

Reform UK spokeswoman Ms Widdecombe was having lunch when Kerry allegedly burst into her home in Haytor on Dartmoor, Devon, the Old Bailey heard previously.
Ms Widdecombe was struck 21 times on the head with a hammer, Westminster Magistrates' Court heard.
Kerry, from Rotherham, South Yorkshire, was arrested on suspicion of murder on 11 July, two days after Ms Widdecombe, 78, was found dead at her property.
He was also arrested on suspicion of the commission, preparation or instigation of acts of terrorism - but has not been charged with this offence.
Kerry will appear at the Old Bailey on 9 October for a case management hearing before a further plea and trial preparation hearing on 20 November.
A provisional trial date was listed for 8 June 2027.
An IOPC spokesperson said of the burglary investigation: "We can confirm that the IOPC has decided to independently investigate the conduct of a Counter Terrorism Policing London staff member following a referral received earlier today.
"The conduct relates to an allegation the individual failed to identify and pursue a line of enquiry relating to an attempted burglary reported in April 2025.
"Counter Terrorism Policing London has been notified of our decision, and no further information is available at this early stage."
According to the National Pharmacy Association (NPA), which analysed data from local health bodies from 2024/25, wasted medicines cost the NHS at least £480m a year.
NPA chair Olivier Picard said that the sums "could be invested in better services for patients," and cited "environmental and health consequences... we can do much more to tackle this growing problem".
The association - representing 6,000 independent community pharmacies in the UK - is calling for patients with several repeat prescriptions to have more reviews, so medicines that are no longer needed can be identified.
Mr Picard added: "We are urging patients only to request medicines if they really need them when ordering repeat prescriptions.
"As well as this, patients who are prescribed multiple medicines should have these more regularly reviewed to ensure they are being fully utilised.
"If a patient has any concerns about their medicines, they should speak to their pharmacist, who can help them get the most out of their medicines."
Medicine shortages across England reported
It comes after patients and pharmacists have struggled in recent years with medicine shortages, with Community Pharmacy England (CPE) reporting more than 1,500 shortages across the country between May 2024 and April 2025.
In a meeting with MPs this week, the CPE's Dr James Davies said pressures are persisting this year, increasingly due to economic factors, as well as manufacturing and supply chain issues.
He added in a statement on the CPE's website that "community pharmacy teams, as the front door to the NHS, continue to shoulder the impact" of medicine shortages.

Dr Davies said that "it is deeply concerning that little meaningful progress for patients has been made", and noted a recent survey from the CPE "found that 86% of pharmacies are spending more time sourcing medicines than they did a year ago, with 72% of pharmacy team members reporting that patients are affected by medicines shortages on a daily basis".
He added: "These findings underline the urgent need for reform of the medicines supply system.
"At a minimum, the government must deliver on its commitment to introduce pharmacist flexibilities, enabling pharmacists to make appropriate amendments to prescriptions and help mitigate the impact of shortages on patients."
Jack Diggle, 23, Craig Shackleton-Brady, 26, Andrew Roberts, 24, and Benjamin Dooley, 23, were all pronounced dead at the scene in Huyton, Merseyside, in the early hours of 24 July.
Police were called to reports that a black Seat Cupra had crashed into a lamppost on East Prescot Road.
At the time, police said a 27-year-old man who was a passenger in the car survived and was taken to hospital.
In an update on Friday, Merseyside Police said James Diggle, 27, has been charged with four counts of aiding and abetting causing death by dangerous driving.
Diggle, of Alundale Road in West Derby, will appear at Liverpool Magistrates' Court on Saturday.
"Our thoughts remain with the families and loved ones of the four men who tragically lost their lives and we ask that their privacy is respected at this extremely difficult time," police said.
The families of the four victims released tributes after their deaths.

Mr Shackleton-Brady was described as a "devoted and loving father" to his two children and as a "loyal and generous" man, who "will be remembered for his kind heart, his devotion to his family, and the joy he brought to others", his family said.
Mr Diggle, who was a proud Everton supporter, was described by his family as "kind, quiet, thoughtful and loving".
His mother said: "The loss of Jack has left a hole in our lives and in our hearts that can never be filled. We will carry him with us every day and miss him for the rest of our lives.
"Our Jack, our gentle giant, we love you beyond words and will love you forever. Rest peacefully, son."
Mr Dooley's mother, Kerry, said her life had been "ripped apart". She said her son was "the kindest person" she knew and that he had "a heart of gold". Mr Dooley's sister, Demi, added that her brother's death felt like "a terrible dream".
Mr Roberts' family said: "Our worlds are shattered, and we just keep waiting for you to come through the door saying this is all a dream, but it's never going to come.
"Life can change in an instant, and Andrew's passing is a painful reminder of how precious every moment really is."
