Chelsea always following neymar situation year after year though.
Next season could be a decider for him personally to choose to stay at psg or move elsewhere to a club with huge ambitions and past history to win things. Manchester united and chelsea keen to sign him but for now it would cost a lot so yeah keeping him on the radar is the best action they could do. Ligue 1 will never be the same without messi leaving and now mbappe on the verge to leave as well.
Neymar will move to MLS most likely, maybe he will follow Messi to Inter Miami or another team but his departure from PSG is almost sure. The number of injuries taken by him will make him think twice before playing again with PSG.
After Neymar and Messi, mbappe will start thinking about moving to Real Madrid eventually.
