Ageuro would be an excellent buy, with Defoe being of small stature, with pace, Ageuro is very similar, so we would still need a bigger target man, that the smaller strikers can play off, and I don't mean Crouch, tactically with his freakish height he gives us another option but I don't think he is good enough to start, he is not clinical enough, if Athletico are asking 20-25m for Forlan, they would ask at least 30-35m for Ageuro at only 22, he is a very valued player, I think Athletico would be smarter to let Forlan go for a big fee, and keep Ageuro, at 31 Forlan, he has only a few seasons left, Aguero will develop in to a world class striker, and could play another 10yrs.
Unfortunately after Forlan's recent comments I am not confident we would get him, and we have even less chance of bagging Aguero.
Our top striker transfer targets should be
Dzeko, Suarez, Fabiano, Forlan
Forlan is the most likely of this group, and if we don't get any of these
Cardozo, Cavani, Falcao, Agbonglahor
A few may frown at the latter mentioned but Agbonglahor at 23, scored 13 from 35 last season for Villa, in the top 10 for EPL scorers last season.
