Sorry, but that is just rubbish.
At a push you could say there are three teams worth anything in that league, even then At.Madrid were never going to win it or come close.
Serie A is by far and away the better of the leagues, they are going through a bit of a bad patch right now but teams like Juventus, AC and Fiorentina and then the ones just below them are a lot better than the ones behind Real, At.Madrid and Barca.
I would also argue Cavani is technically better than Falcao. Falcao is no Heskey but Cavani has superior skill on and off the ball imo.
