Or his departure is one of the reasons nobody wants to pay
Anyway, I think this belittling of other leagues is pointless. Had Neymar joined Lyon or Marseille and won them Ligue 1, it would have been a different story. But joining a team that is so far ahead of the domestic competition made it all about UCL glory.
I think in his first 3-4 years at PSG, Neymar when fit was second only to Messi. But he was never really challenged playing in Ligue 1 and was sidelined by injuries that definitely had tondonwith his lifestyle and his lifestyle had to do with PSG.
All in all a terrible career move and a real shame. But I wouldn't blame it on the league, that's too easy.
