Theo Walcott has added a ruthless streak to his forward play this season, according to Arsène Wenger.

The 21-year-old enjoyed a flying start to the campaign with four goals in his first two starts before an injury suffered on international duty stopped him in his prime.

Walcott returned from his lay-off with a bang, scoring twice at Newcastle in his first start for six weeks. Both Carling Cup goals were taken with aplomb and Wenger likes what he has seen.

"I am highly encouraged by Theo's performance since the start of the season," said the manager.

"He has done extremely well, he has come back and played 90 minutes [against Newcastle] and finished the game quite strong.

"We will have to get him slowly back to his best and he will be a tremendous asset for us in the whole season.

"There is a big difference in him because he has become more clinical. His passing is better, his finishing is better, his runs and resistance to body challenges is much better so he is there."
