Berba would be great. Short term fix, yes, but a class act that would be fantastic in the side - particularly when supported by the midfield.

Best other shouts I've heard would be a loan for Morata, or Aboubakar from Lorient (dat Arsene French connection).

Remy would be my personal long-term preference if QPR don't demand 15-20mil.

Mandzukic would be great in the summer also.

Before Arsene signed Ozil I'd say none of these options will ever happen, but nowadays I don't know what/how to think with Arsene & transfers.
