I have to disagree, Torres was on a big spiral the back end of the 09/10 season and right through the next season. His only decent game was scoring two against us, other than that he was complete cack.
The problem with Roman is he is being advised to buy the complete or in Torres case, formerly complete articles. When moulding a player into world class is the better option.
We signed Shevchenko when a young Torres would have been better, then we signed Torres when Aguero or Suarez would have been better, both going on to prove their worth in the Prem at our rivals.
Cavani is a risk, but he is in form when we are signing him and a good age.
