He's a player i so much admired cause of the great talent he has but injury didn't allow him to harness his full potential, he's a great player and can be compared to the likes of Ronaldo and Messi, if only he didn't make that move to PSG and remained at Barcelona back then i feel he would've had a more wonderful football career like Ronaldo and Messi. It would be very lovely to watch Neymar play again, i miss those skills, he's was a very big threat to defenders but i doubt if he's still got it in him, am not even sure that he'll be fit enough to feature in the world cup moreover it's a big competition and the coach won't want to risk involving a player that can't be much reliable when it comes to fitness.
Neymar departure from Barcelona was the right move as he wouldn't be able to achieve greatness while playing in the shadow of Messi. Everything was being done for Messi to get the glory at Barcelona and neymar needed his own acknowledgement. It's just sad that the move to PSG didn't favour him and that was as he didn't move to a top club in the more important leagues but went to a farmers league that not many people watch the league. Neymar lacks the discipline that Ronaldo and Messi has, he still wouldn't be able to reach his full potential regardless of which club he went to but any other clubs would had been better than that PSG that he went to, to end his career.
Neymar made his football recital with Santos in the Brazilian league.
When he came to Barcelona, he didn't have such a great football.
Maybe, as you said, he was in Messi's shadow.
He may not have had enough support in the team, but if he had gotten stronger, he would have stayed, fought and made his mark at Barça, but he didn't do that. He went to PSG.
PSG thought that if they got Neymar, they would be champions of the Champions League, but that didn't happen either. Now he's at Al Hilal, but football has been a long time since Neymar left. He's gained a lot of weight. He doesn't take care of himself either. He's a shame for himself.
