How can I explain when you don't want to read?
If you know what kind of player he is, than how can you say he is not creative? You are basing your opinions on statistics only... I'm lazy to look, but im cretain he has over 10 assists every year since he came to Napoli, check if you want. So, even the statistics is not bad at all. And i really, really don't know how can you judge someones creativity by his assists
Pirlo except this season has never had more than 5 assits per season, does that mean he isn't creative?
Every action Napoli makes is trough him. Him or Hamsik. Do you know how many chances he created to Cavani? At least 3-4 per game. If Cavani have scored everything Lavezzi created, he would have had like 30 assists so far...
He has also pace and acceleration, he is arguably the fastest player in Serie A atm. Bare in mind he plays in the hardest league for fast players like him. Also, have you seen that whenever he has the ball, at least two players are around him? Well, if you didn't know, that creates SPACE for the other players.
Not to mention he is not selfish, always passes the ball, rarely keeps the ball with no need... And you said the stamina, the workrate, and the fact he goes back to help the defense. Would be perfect for 4-2-3-1, or even 4-3-3. PERFECT. Serie A proven player. The player with least chances of being flop than every other players we were/are linked to.
The only neagitive that would be in this eventual transfer is his price, nothing more, nothing less...
edit: I was just watching the highlights from serie a, did you see that assist to Pandev 2 days ago? Damn...
