Dzeko is better than Lewandowski in my opinion and I really don't know if we could turn his head, but I would definitely take him over Suarez. I think that type of striker is better for our collection of players. Plus he can finish left, right and with his head. I would fancy him for 25+ in the league here easily and we wouldn't lose much of the team cohesion.
But anyway, looks like we're going all in for bucky o'hare and will get him, so whatever.
