Honestly I'm still very sceptical about all this. I think Neymar just loves the attention it builds from all the media headlines, although this has dragged on longer, it's been the same kind of rumours every pre season with him. So many times in the past we've seen "official confirmation imminent" from usually reputable sources only for nothing to ever materialise. Secondly why would Barca let a player have pre-season with them if they know they're about to sell as some news outlets are saying, not even this incompetent board would go that far. In terms of his play style, he either amazes me or frustrates me greatly. Sometime he stagnates attacks by holding on to the ball for too long or only searching for Messi. If rumours about him wanting to be main man are true, I can imagine him going back to the more selfish style of play we saw earlier in his career where attacks are either lethal or break down. His form in 14/15 was so lethal in my opinion as he became more direct in play style.
I honestly can't see him leaving but at the same time wouldn't consider PSG any closer to being CL contenders with him in the team.
