Yeah, well, he's a well known anti-Croat and i think back in the 90's he was the most hated football player in Croatia. ( it's funny because his mother is a Croat)
I also disliked him very much, as a man, and i hated him for being so damn good from set pieces. But i respected him as a player.
His corner kicks were indeed a master piece. Even if the ball didn't go directly into the goal, the way he curved it and considering how fast the ball was going, it needed just the slightest touch to change direction (from anyone, not only from the players from his team) and to end up into the net.
I remember that Lazio scored many goals from the CK's he took.
