The problem with Dzeko is he's a fantastic striker with great skill and a real eye for goal, somedays a worldbeater. But he's a confidence player and at the moment he does'nt have any so he looks poor and puts us under pressure more often than not. I am a big fan of his but in recent weeks he's been a weak link. I put part of the blame at Bobby's feet though, he rotated when Dzeko was flying and he's never got that form back! He's getting the nod over Mario because of the system we are playing, needing a big man to hold the ball. IMO Mario should be starting because when he comes on as a sub he feels the need to get involved and put himself about, as much as i love Mario he isn't a tackler and will get himself booked easily, but when he starts games he seems to grow into it because he has plenty of time to do work his magic!
