Arsène Wenger says Jack Wilshere should not worry about scoring goals - because he will become more prolific with experience.

The England international broke the deadlock against Montpellier on Wednesday night with a clever finish from Olivier Giroud's header, taking his tally to four in 69 first-team appearances.

Wilshere was a regular on the scoresheet as he emerged through Arsenal's youth ranks and Wenger thinks first-team goals will come naturally.

"It [Wilshere's scoring record] will get better," said the manager.

"In his first season he became obsessed, well that is a big word, maybe a little bit disappointed that he didn't score more goals.

"He focuses on what is important for a midfielder: defend well, make the team play well and then he will get on the end of things. He showed that last night."

Wilshere's celebration at Emirates Stadium of Wednesday spoke volumes about his joy at ending his 17-month injury lay-off. Wenger always expected the 20-year-old to return - but perhaps not so soon.

"It’s fantastic," he said. "I always said if we have Jack back in January, we [would] have done well. He has done much better than expected.

"What is good to see as well, is that he can absorb games now. I don’t forget that he has been out for 17 months and that we still have to be a bit sensible."
