If you mean the potential he had when he was at Inter and Man City, I don't think so. He could have been one of the best strikers in the world but his attitude and work rate are terrible so he doesn't try enough. I think he could get back to how good he was at Inter (which is most likely his potential now) but that would need a drastic change in his mentality. He's 25 now so he's got 1-2 years to prove himself otherwise his career will go into a massive decline.

He has scored so awesome goals for inter milan and also AC milan, he had a very minimal impact whilst at liverpool, i guess he could reach a peak in his career, but he needs to increase his effort and morale
