Arsenal boss Arsene Wenger admits his young defensive players aren't ready for the Premier League.

Arsenal twice came from behind to salvage a 2-2 draw in Sunday's friendly with Hong Kong champions KitChee.

Wenger, who used the likes of Craig Eastmond, Kyle Bartley, Ignasi Miquel and Nico Yennaris at the back, said: "I think defensively we looked fragile, especially in the first half.

"In the second half not so much because we were not challenged. Defensively we have a lot of work to do as a unit to do much better.

"We let everybody play and some players are not yet at the level of the Premier League. It is a learning process. If you don't do it in pre-season then you never do it - you give them a chance to see what is requested at the top level.

"I played all of the defenders during this tour to see who is ready and who is not. We have Bacary Sagna, Laurent Koscielny and Per Mertesacker at home - three experienced defenders."
