I would like to see the outcome if Capello had to coach a side like Lecce or Fiorentina, and then be succeeded by Jose Mourinho just to compare results. It would be interesting indeed.
Mourinho basically built the 2004 Porto sqaud all by himself, and he was the master behind improving individual talents such as Deco and Riccardo Carvalho. I am not sure if Capello is adept enough to take a side like Porto and build them into a European Champion because he can only make do with what he has and what is provided to him, while we have seen what Mourniho can do in that respect. Therefore, combine this information with his resume, and you will see that Capello is no where near the best coach in the history of football...obvious really.
