Arsène Wenger has revealed the latest information ahead of the AC Milan game:

on Per Mertesacker...

He had reconstruction of his ankle in Germany before he joined us and the scan did not look too positive yesterday. Last night he went back to Germany to speak to the specialist and see where we go from there.

on Jack Wilshere...

The recovery of his latest problem looks very, very good. His last scan was very positive so we go here cautiously, step by step, because we tried to push him back quicker and we had a setback. This time we have to be very cautious and not go too quick. He can be back before the end of the season, of course.
