Not that I believe anything that originates from Twitter but all of the top tier players most likely to move this summer, M'Villa is the one we stand the best chance of signing in my opinion.
Him, Podolski and another attacking player like Dempsey or Suarez would be a good summer. Could do with another CB but with 4 internationals currently at the club it seems unlikely. An experienced LB would be nice as well but I can't see Wenger giving up on Gibbs just yet.
