Chelsea could win title after Man Utd loss - Ferguson

Ferguson conceded that his side's display in London on Sunday was "low key"

Sir Alex Ferguson criticised referee Chris Foy after seeing his Manchester United side lose 1-0 at Arsenal to leave the title race wide open.

Though conceding Arsenal had a case for a penalty, the United manager bemoaned Foy's failure to give the league leaders one of their own late on.

"It gives Chelsea a major chance now - and that's what happens when you get these decisions," he told Sky Sports.

Chelsea trail by three points but will go top if they beat United on Sunday.

Foy missed a clear handball from Nemanja Vidic with Arsenal's Robin van Persie poised to glance Theo Walcott's cross at goal before half-time.
