Phil Jones and Daley Blind found themselves in hot water immediately after Manchester United won the Europa League in May.
The pair were both punished for breaching UEFA rules after they failed to promptly report for a drugs test after the final whistle.
They were fined €5,000 but Jones also received a two-match ban for allegedly verbally abusing a doping control officer during the incident.
Initially, it seemed a fairly harsh ban. After all, you can understand why players would be so keen to celebrate winning a major European trophy.
And this one had even greater significance, as the game took place just two days after the terrorist attack in Manchester.
Although he did not feature in the 2-0 victory over Ajax, Jones had wanted to pose for a photo with the rest of the United squad to pay tribute to the victims of the attack but was not allowed to do so by the doping officers.
It has now been revealed exactly what the English centre-back said to the officer that prompted the subsequent ban.
Graham Stringer, MP for Blackley and Broughton, wrote to UEFA president Aleksander Ceferin regarding the clash three days after Blind and Jones were issued their fines and Manchester Evening News have been able to get their hands on the response, which includes details of the X-rated rant.
"The first player from Manchester United, Phil Jones, came to the DCS (doping control station) and was very upset that he had to be in the DCS," Luka Zajc, UEFA's head of president office, wrote.
"He wanted to leave the DCS to celebrate with the team but I told him that he had to do the sampling first.
"He then told me I was a f***** doing this and that I had a f****** job and how I could be so f****** stupid to consider having such a f****** job."
"I told him that this was the UEFA regulations and that my job was to do the control. He still continued to tell me I had a f****** job and how I even could do that job.
"I then asked him to calm down and stop insulting me and then he said he didn't want to talk to me anymore."
The reply also revealed that Jones should have actually received a three-match ban but UEFA showed leniency, given the circumstances surrounding the match.
United appealed against the ban and asked if Jones could be granted special dispensation to play in the Super Cup earlier this month but their request was rejected.
