Arsenal winger Theo Walcott has no doubts Europe are fearing their young team after last week's 5-0 thrashing of Champions League opponents Porto.

The Gunners looked unstoppable as they cruised into the last eight, despite missing key players including influential ­skipper Cesc Fabregas.

Walcott said: "Five-nil will have an effect on other clubs - hopefully they will be wary of us.

"Arsenal is a big club - every club that plays us fears us.

"We've got great people going forward, great ­defenders. You look at the way we played, we took all our chances and ­defended very well. Thomas [Vermaelen] was throwing his body in places where you wouldn't want to see. It was teamwork and it went fantastically well."
