All the talent in the world. For me more talented than anyone in his generation but Messi. Achieved a lot but should have achieved so much more. A shame.
It isn't hindsight as plenty of us said it at the time, but the move to PSG in summer 2017 was a demarcating point. The league is good but simply not watched or respected (by others, not me) enough to sustain a player of Neymar's calibre. Mbappe found that out too.
I get that he wanted to get out of Messi's shadow, so to speak, but he should have stayed at Barca (looking solely from a playing perspective, not financial).
