So, apparently we are still interested in Neymar.
He is a difficult one to judge. His abilities and style could fit us perfectly. He could rule the left side like Ronaldinho once did and if he developed as a player as he very well could no defense in the world could hold Messi, Neymar and a third hardworking striker, backed up be a central midfield with the likes of Xavi, Iniesta, Cesc or Thiago. He can create a goal own his own like Messi, take on a cuple of defenders and so on.
Tragically, he just seems to be a complete idiot with an oversize ego, and he would really have to get that under control if he should wear the Barca shirt. Otherwise it's not worth the risk. And tragecally for him Barca would be the far best place for him to play, because here he could learn and his style could fit much better than at chelsea. He is almost designed to be the next great left attacker in Barca. Perhaps Pep has the authority to bring him down to earth, but it's risky.
I do feel though, that he could really become the second best attacking player in the world - nobody will beat Messi as long as he's around.
