Arsenal boss Arsene Wenger has concerns asking too much too soon from Alex Oxlade-Chamberlain.

The Frenchman is anxious to avoid a repeat of Jack Wilshere's first full season in the first team, which meant he could yet miss all of this campaign with an ankle injury.

Wenger said: "At the start of the season you think: 'I will play him 20 games, maybe 25.' That's what happened to us last year with Wilshire.

"When they deliver a performance they play 45 (games) and then they play for the national team and then they get injured.

"It's about trying to find the right balance between having confidence and not being too early and too much under pressure."
