Give the young lad a chance.
Look at Sven's track record over years, every time there is a major tournament he seems to take an untried, but potentially massive, youngster. Maybe he wont play many games, is that the point? the point is to give him the experience of this type of situation and learn from more experienced pros.
If im wrong I hold my hand up, but if this lad is good enough for Arsene and Sven, that'll do for me
