Arsenal midfielder Jack Wilshere has been charged with misconduct by the Football Association following his anti-Tottenham chants during the FA Cup victory parade on Sunday.
The 23-year-old, who came through the Gunners' youth ranks, took to the microphone to mock the club's fierce rivals as the players celebrated on a stage outside the Emirates Stadium.
In similar scenes to 12 months ago, Wilshere then proceeded to lead the massed ranks of Arsenal supporters in a chant which included expletives against Spurs, who again finished below their north London neighbours in the Barclays Premier League table.
On Monday, Wilshere apologised if his actions had caused any offence and was spoken to by Arsenal staff on the issues.
However, the FA has now launched formal disciplinary proceedings.
A statement read: "Jack Wilshere has been charged with misconduct in relation to Arsenal's FA Cup celebrations on Sunday 31 May 2015.
"It is alleged his conduct in making and/or inciting certain comments during the club's open bus trophy tour was improper and/or brought the game into disrepute.
"The player has until 6pm on 10 June 2015 to respond to the charge."
