It was a frightening scene at White Hart Lane in London as Bolton Wanderers midfielder Fabrice Muamba collapsed during an FA quarterfinal match against Tottenham on Saturday.

Bolton confirmed that Muamba, 23, suffered a heart attack. He is in critical condition at the intensive care unit of the heart attack centre at the London Chest Hospital in Bethnal Green, which is nine miles from the stadium.

Six medics treated Muamba on the pitch for about six minutes. They gave him mouth-to-mouth resuscitation, and tried to revive him with a defibrillator. The Zaire-born star was removed on a stretcher wearing an oxygen mask, and then taken to the hospital.

Muamba fell with no player around him at the 42nd minute of the match, which was suspended a few minutes after referee Howard Webb consulted with both clubs' managers.

The Football Association quickly expressed support for Muamba's recovery.

On behalf of The FA, I would like to send our thoughts and prayers to Fabrice Muamba and his family this evening, said FA chairman David Bernstein in a statement. Fabrice has played 33 times for England Under-21s, captaining Stuart Pearce's side during this time, and is a player, and more importantly a person, we care greatly for. We are in contact with Bolton Wanderers over Fabrice's condition and are awaiting updates.

Many Premier League players have expressed their best wishes for Muamba.

We are all Wanderers tonight, posted Frank Lampard, of Chelsea, on Twitter.

Kyle Walker of Tottenham posted on Twitter: Doesn't matter who you support. Doesn't matter if you aren't a football fan. Doesn't matter if you aren't religious. Pray for Fabrice Muamba.
