I'm quite ambivalent on Lewandowski. For me he seems a similar player to Dzeko and thats not a good thing. If Berba goes, which he most likely will, then its possible we need another striker. However it depends what happens with our midfield. If we somehow pull off the Modric deal, which I doubt, but if we do then along with Kagawa, and of course Nani, Young and Valencia we'd be able to play 1 up front whilst still having a very attacking array of players behind the lone front man. But as I say, the need or not for a 4th striker depends on what else happens in midfield
