Man Utd boss Ferguson: Arsenal defeat helped us

Fergie said: “The Arsenal game gave us a real wake-up call, a right kick in the you-know-whats.

“Sometimes you need that shock to get you back and going at it.

“We’ve had two clean sheets in three games since. And that’s going to be the key to us winning the league.

“We have the players who can score and win matches but we need zeros against our name at the back.”
