Manchester United boss Sir Alex Ferguson believes there are clubs capable of gatecrashing the established top four this season.

Ferguson admits he's unsure who might snatch the fourth Champions League slot.

"I could toss a coin and that could be my best chance of deciding who could break into the top four out of Tottenham, Aston Villa, Everton and Manchester City with all the money they have.

"That's a difficult competition in itself and any one of them is capable of doing that"
