He hasn't looked right for awhile. He seems to be just too bulky. Watch him from 4 years ago, much leaner and quicker, but then again also much more injury prone. Perhaps this bulkiness has helped him stay healthy and I'm thankful for that. In his early years with us, injury prone, but since about the past 3 years, hardly ever gets injured! He's lost a step and that is making it more difficult for him. Still a quality player but you can see the difference b/w him and Jesus very easily, Jesus appears quicker and more lively, although Aguero is still more likely to score than Jesus (more experienced, stronger, and better finisher). Still can be useful for us, but surely we'll be bringing someone in to compete.
I also always find it strange that he feels unsettled due to the presence of Jesus or the fact that Pep may want to bring in additional forwards. When he started with us, he was competing against 3 other quality strikers, Dzeko, Balo, and Tevez he didn't complain then. Why not, because he was top of the heap, because he earned it. He is not earning being on top of the heap now and with a team with our ambitions, it always has to be earned!
