It's not that he's used him badly, but that he does not have the players to bring the best out of him, especially that he's far from his best form due to his injuries. The other striker depends on the Lukaku situation, imo, which looks very complicated at the moment. But if Lukaku is sold, then I definitely think we need a third striker along with Costa and Torres, because I can't see either of Eto'o or Ba staying beyond the summer (although, if I had to choose one of them to stay it would probably be Ba). Cheers
