Arsenal have Manchester United running scared after Saturday's win, says star winger Theo Walcott.

Walcott, 19, insisted: "Everyone knows that Manchester United are a world class team - and we need to make teams come to the Emirates and be scared of us.

"That performance will put fear in people's minds."

He added: "United are just behind us in the Premier League table now, so that win has definitely boosted our confidence and morale in the dressing-room. We're third now, so, hopefully, results will go our way."
