Tomas Rosicky has hailed the goalscoring form of Arsenal teammate Theo Walcott.

Walcott scored twice at West Ham United on Boxing Day and Rosicky says he has matured into a major attacking force.

"The goalscoring threat is the main thing with Theo," he told Arsenal Player. "You can see he is a very good finisher. Since I joined Arsenal - Theo came six months earlier than me - I've seen him grow from let's say the kid when he arrived.

"You could see that he would be good finisher [then], which is what he's showing now. He's a real threat in the box, he's got an eye for the goal so it's very good to have him back because you never have enough guys like that."
