Arsenal manager Arsene Wenger has claimed that he cannot recall Serge Gnabry from his loan at West Bromwich Albion, but has urged the youngster to prove himself at The Hawthorns.

West Brom head coach Tony Pulis recently claimed that the 20-year-old was not at the right level of fitness to play.

The winger has played just 12 minutes of Premier League action and made three appearances since joining the Baggies in the summer.

"Serge Gnabry is on loan for the season," Wenger said in today's press conference. "We cannot get him back before the transfer period. Loans between Premier League clubs are season-long loan.

"I heard that Tony Pulis is not happy with him. He has to change the opinion of Tony Pulis because I think that Serge Gnabry has the quality to play in the Premier League. He has shown that.

"It's good that he faces this kind of battle because it will make him stronger if the turns the opinion of Tony Pulis around. I hope that he's facing the challenge and is putting the effort in."

Gnabry made his senior debut at Arsenal in 2012.
