No, he isn't. He's a clown as you say. But why hate a clown? He's just a silly man. As for his qualities on the pitch, they are definitely still there. I can see why we'd be interested. But all things considered I would not go for him myself.
I'm all for Lavezzi in January on a short term contract. (maybe something like 2yrs + 1yr option) He's a quality player and will definitely help us while we compete on 3 fronts.
As long as he doesn't interfere with longterm prospects.
Saponara or Lavezzi? More quantity over quality... We need an RB and an AM. We shouldn't play with wingers what we need is Morata + Dybala + Pogba near our strikers and that's not possible with two wingers
