#4 Ligue 1 or the Premier League may not suit Neymar's playstyle
Neymar Jr's style of play is fairly set in stone at the age of 25 - the Brazilian is perhaps the player who attempts the most dribbles and take-ons in La Liga... with predictable results.
Neymar's penchant for 'going down easily' is well known, and while the referees in La Liga are predisposed to blow their whistle, he might find that it is not the case in Ligue 1, and especially not in the Premier League.
Moving to the cold & damp Manchester may not sit well with the sunny Brazilian, but even putting aside the weather, Neymar may need to adopt a more direct style in these leagues that tend to not afford as much time on the ball as La Liga does.
Neymar does have the ability to adapt though, and after a bedding in period might reach the peak of his prowess in any league, but that is quite a risky for his short term goals with Brazil.
