I saw Atlético Madrid play this season against my local team Osasuna, and the standout player was not Falcao (who I was at that point imagining he would be playing blue next season), but this guy.
Perhaps it wasn't representative of the whole season, but in that game Costa was the better player, and I think in Spain it has been recognised that he has had a great season. He's very aggressive, but I don't think he's a tool in the vein of Rooney, van Persie etc. As for being Brazilian, I think he would have no problem whatsoever fitting into the Prem, because as I said he's a very strong player who won't go down at the slightest push. In fact, I think he will probably do the pushing...
I think this could work, you know.
