The FA has made contact with former Manchester United striker Wayne Rooney, after the Derby County boss admitted to wearing longer studs in a 2006 match against Chelsea 'so that he could hurt someone'.
The Rams boss claimed that Chelsea's superiority over Manchester United frustrated the Merseyside striker to the point that he changed the stud length of his boots for their Premier League clash.
According to the Athletic, the Football Association have said they will investigate the claim made by Rooney and have recently gotten in contact with the 36-year-old.
16 years ago, Rooney and Manchester United travelled to Stamford Bridge to play Jose Mourinho's Blues who needed just point to win the Premier League title.
Sir Alex Ferguson's side fell to a 3-0 defeat that day as Chelsea went on to win the league, but not before Rooney could leave his mark.
The former United forward, speaking to the Mail On Sunday about the game, said: 'I changed my studs before the game.
'I put longer studs in because I wanted to hurt someone.
'If Chelsea won a point, they won the league. At that time, I couldn't take it.
'The studs were legal. They were a legal size. But they were bigger than what I would normally wear.'
Rooney and John Terry clashed during the game - resulting in the Chelsea defender receiving treatment with his sock being stained with blood.
The Athletic reports that the FA have asked Rooney for his observations around his claims.
