That too but I think the difference between the Dutch league and the Italian league is often underestimated by Dutch players moving there.
In Holland, there's an attacking minded play. Teams go forward the entire match long and if forwards miss a shot, that's alright because there will be others. If a keeper lets one ball hit the net, it's nothing out of the ordinary - he's probably already made a dozen of good saves and the rest of the team will go forward again to claim a goal on the other end of the pitch.
In Italy, it's different. Strikers may only get two chances per match and are hence trained differently and in practice they are more accurate, more sharp than Dutch strikers. Keepers on the other hand may find it difficult to deal with that.
