Wilshere has missed the entire season so far after suffering from a stress fracture in his right ankle and then suffering second stress fracture in his heel when rehabilitating his ankle.
With the end of the season creeping up fast, Wilshere faces a race to become fit and get some Premier League minutes under his belt in order to be fit for Euros.
Wenger said on Wilshere to official website Arsenal.com:
I will not take any risks with him. He is making slow progress so we still have to monitor the situation a little bit at the moment.
As I told you last week, the next three weeks would be decisive and now we have two weeks in front of us. I cannot tell you more.
As much as I would love to see Wilshere back in the Arsenal team and even in Euros, it is imperative Arsenal get his recovery right the first time.
The potential for injury recurrence is always high if players are returned earlier than they should have been, which was evident with Fabregas always re-injuring his hamstrings. We definitely don’t want this kind of injury curse for Wilshere!
