Barcelona and Real Madrid.

[twosips]

Using Simeone's Atletico as proof that Barca would struggle is a bit misleading. Atletico have vastly better footballers than most 'clogger' premier league teams, and they're more organised than most too. They take that English format, yes, but they do it on a higher level than the likes of Moyes' everton did. Besides, Atletico stopped Barca once. They won't again.

Barca would muller the vast majority of teams, and most still simply wouldnt get the ball of them. Theyre the best team in the world.
