Neymar's future is still uncertain at this moment. So many clubs have been linked to his movement in summer but i personally prefer to see neymar make a move to the EPL rather than try to stay even longer in PSG.
I just hear that if neymar was not interesting in moving to the EPL clubs. It seems like that there will be two options for him in summer which is staying even longer with PSG or try to go back again to the barcelona. I don't think the second option was possible due tot he financial crisis of barcelona.
I think that if neymar will be under pressure if he will still continue to stay in PSG even longer. Barcelona has become the main hope for him right now but barcelona is focusing to get another player like gundogan which was decreasing his chance to go back again to the barcelona.
Neymar must accept the fact that if he will not be able to go back again to the barcelona.
There is no certainty about Neymar's future, but he will probably stay at PSG for the remainder of his contract before moving on to another team. PSG knows Neymar will not just leave even though he is rumored with several Premier League teams, but I believe Neymar will still be in the PSG squad next season.
About Neymar and Barcelona, I think transfers are difficult even if they are possible. Barcelona are struggling with finances and they can do little to sign many star players until an agreement is reached for low wages. After all, Barcelona doesn't have enough budget to sign Neymar, but if Barcelona sell of one of the players between Ansu Fati and Ferran Torres then they can sign Neymar.
