Tottenham Hotspur [ Images ] manager Harry Redknapp [ Images ] has criticised Wayne Rooney [ Images ] after the Manchester United [ Images ] striker was charged with using foul language while celebrating a goal in Saturday's 4-2 win at West Ham United.

The England [ Images ] international faces a two-match ban if he accepts the charge, which would rule him out of United's league match against Fulham [ Images ] and the FA Cup semi-final against Manchester City [ Images ] at Wembley.

"Why is he so angry?" Redknapp asked at a news conference in Madrid on Monday ahead of Tottenham's Champions League [ Images ] match against Real.

"I don't remember Bobby Charlton doing it when he scored," he added, referring to the former United and England midfielder, a World Cup winner in 1966.

"Why do they have to be so angry with the world, these young footballers earning hundreds of thousands pounds a week?"

"I respect him a great deal as a player but he's a silly boy and he shouldn't have done it."

Rooney apologised for his outburst soon after the match, saying he swore in the heat of the moment after completing a 14-minute hat-trick.
