Arsène Wenger is confident that Theo Walcott will overcome the psychological hurdle of his latest injury.

The Arsenal forward has been hugely unlucky with his fitness in the past year or so, missing large chunks of last season with a string of different injuries.

Walcott has been back to his best since the start of the new campaign, flourishing after a full pre-season and scoring four goals in two starts, including a hat-trick against Blackpool.

But the 21-year-old is back on the sidelines after hurting his ankle while on England duty in Switzerland this week. 

Walcott has already proved he can rediscover his physical peak after lengthy lay-offs but will this latest knock play on his mind when he returns? Wenger believes it won't.

"The mental side is always a question mark when a player get injuries," said the Frenchman. 

"When you are a manager and you see an injury doesn't harm the career of a player, you are happy. 

"After that the only unknown quantity is how much it will damage his confidence in the box, on tackling and all that. 

"I believe Theo will deal well with that because he has done it before. Ideally, you do not want a player to be injured many times by bad tackles."
