Manchester United legend Sir Bobby Charlton has urged supporters of England not to pin all their hopes on Arsenal midfielder Jack Wilshere.

Despite the fact that he is just 21 years old, Wilshere has been tipped to be England's key player during next year's World Cup in Brazil - providing that the Three Lions qualify for the tournament.

However, Charlton believes that while Wilshere is a "great player", England's hopes of success should not be placed solely on his shoulders.

"I think he's just too young. It's just too soon for him on the world stage," Charlton is quoted as saying by the London Evening Standard. "Arsenal have a lot of young players, and very good young players at that, but there's something that's just not quite right, it seems to me.

"Don't get me wrong, Jack Wilshere is a great player but there are lots of great, even greater, players on the world stage, who are outperforming him. He's still a young lad who needs more time and we'd be wrong to pin all our hopes and expectations on him."

Wilshere has made seven appearances at senior international level.
