What do you mean? If you're talking about Osvaldo of Fiore and Bologna, then yes, he is a different guy nowdays. His spell in Spain made him a much better player.
People who watched him in the Liga last season said he improved a lot. I don't think he's been that good this season, but he's certainly improved from the Osvaldo we used to see in Fiorentina and Bologna
Bojan in, finally a player who at least will move around. So far the only player constantly willing to get past his man (that actually is fast) is Jose Angel.
