Aguero has never stated that he wanted to go to Real Madrid. In fact I've yet to find an article on NewsNow that says that. Plus a fact, that he plays for Atletico, a known rival, so why would he go there anyway? And why would he go there now, since Madrid are at the moment, better off selling their attackers rather than gaining them (e.g. Robben, K-JH, VDV, and RVN.)
Villa is a great striker, but he isn't a "young" striker, while Ibra is just an overrated piece of shit!
