The Professional Footballers’ Association has launched an investigation after its team of the year announcements were leaked ahead of its awards dinner.
Line-ups appeared on Twitter on Thursday, prompting the PFA to bring forward confirmation of its line-ups which had been due to be revealed on Sunday.
The individual player of the year announcements were not leaked.
The PFA, which is headed by chief executive Gordon Taylor, will look at how the information made its way into the public domain, firstly by seeking answers from printers of its awards ceremony brochure.
The Times reported a Twitter user had received the brochure and posted the teams online, where they were widely shared.
In a statement on its website, the players’ union said: “The PFA is disappointed that a member of the public has chosen to deliberately leak our representative teams from the official brochure of the awards evening.
“As a matter of urgency, we are seeking a detailed explanation from the brochure printers as to how they were able to secure a copy of the publication.
“The unveiling of the PFA representative teams is eagerly awaited by our members and football fans throughout the country and we hope that the unfortunate leak does not affect the wide-ranging debate and discussion which accompanies their normal release on the day of the event.”
