Theo Walcott urges Arsenal to move on quickly after Champions League setback

"We need to move on now. We have got a big, important game at the weekend."

Theo Walcott has challenged Arsenal to put their nightmare Champions League trip to Dinamo Zagreb behind them by returning to form against Chelsea at Stamford Bridge on Saturday.

The Gunners had striker Olivier Giroud sent off as they crashed to a disappointing 2-1 defeat at the Maksimir Stadium.
