I wonder why you say so, Neymar may not be the most loved player in the world, but I do not think he's that hated, the lad has got trailer load of talents, he just needs to keep his head down and be focused.
I have no doubt in his talent and quality. But he spends a lot of time rolling around on the pitch pretending to be injured or badly hurt and I hate that. He is ridiculous with his nonsense dribbling attitude that makes him look like a circus freak. I am pretty sure he is the most hated player today, both from opposition fans as well as professional players. A few months ago a defender said in an interview that he injured Neymar intentionally because he was trying to make his team look bad. I think it was a Nantes player but I am not sure.
I'll have to agree with sarri on this one, I think if juve are to accomplish what they so crave for, and that's the UCL, they need a better left back, someone with more qualities than Luca, though he's a decent lad, but I think they need more(quality).
In that case I don't understand the decision of bringing Pellegrini and selling Spinazzola who I think is a better player compared to Luca. He even has plenty of qualities to push Alex Sandro to the bench especially in attack.
