Arsenal star Jack Wilshere was fined £40,000 (55,900 euros, $62,900) on Wednesday and warned over his future conduct after being charged with making controversial remarks about rival club Tottenham.

The 23-year-old England player had taken to the microphone and led fans in two crude chants about their arch rivals during an open-top bus parade, a day after Arsenal's 4-0 win over Aston Villa in the FA Cup final last month.

"Arsenal's Jack Wilshere has been fined £40,000 and severely warned as to his future conduct after admitting to a charge of misconduct," said a statement released by the Football Association.

"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 Arsenal's youth system, had already expressed regret over his behaviour.

"Sharing back2back Cup wins with so many amazing Gooners is a dream come true. Apologies if I upset or offended any of u with my celebrations," he tweeted in the aftermath of the incident.
