Arsenal midfielder Jack Wilshere has been fined £40,000 and severely warned as to his future conduct after admitting a charge of misconduct, the Football Association has announced.
The England international sang anti-Tottenham chants during the club's FA Cup victory parade, taking to the microphone to mock the Gunners' fierce rivals with a foul-mouthed taunt as the players celebrated on a stage outside the Emirates Stadium on May 31.
"Arsenal's Jack Wilshere has been fined £40,000 and severely warned as to his future conduct after admitting to a charge of misconduct," read a statement on www.thefa.com.
"Wilshere was found guilty of making and/or inciting certain comments during the club's open bus trophy tour after their FA Cup Final victory, with his conduct deemed to be improper and bringing the game into disrepute."
Wilshere, who came through the Gunners' youth ranks, led 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.
The 23-year-old was subsequently reminded about his responsibilities by the club and also then issued an apology via Twitter for any offence caused.
This is not the first time Wilshere has found himself in the headlines for the wrong reasons, having been pictured smoking in a Las Vegas swimming pool last summer and then spotted holding a shisha pipe on a night out in February.
Talking about the parade incident last Friday, Wilshere said: ''I have always had that bond with the Arsenal fans since I was young because I came through the club.
"I grew up at Arsenal and I love the fans but, believe it or not, I have actually got family who are Tottenham fans so it's nothing personal against them, it was just a bit of fun.''
Two days later, Wilshere went on to open his England account by scoring twice in the 3-2 win in Slovenia on Sunday.
