That's still too fast I think, even though in this case what you say about Neymar's injury is clearly disturbing but still retiring too early now is not something Neymar can do.
I still see he can still be for some clubs in Europe, only if he really wants to be glimpsed quickly so he must cut a little for his salary, then there will indeed be some big clubs that will glance.
It seems that Neymar did say he wanted to retire in a few years. But indeed maybe this will be too soon if this season. In some rumors, I think I've heard that Neymar is interested in moving to Man United. Maybe this will work, but indeed his salary is still quite high, moreover, his current performance has decreased, one of which is due to the prolonged injury he has experienced. So, maybe some clubs will think hard about this. He can still play very well, but not as excellent as in several seasons previously.
Neymar still has a contract with Paris Saint Germaine that's still valid beyond the summer and I think he's not in a haste to leave PSG at the moment. Speculations about his future has been in the media space for sometime now but none of the speculations has been reported to come from him or has any of them come from his club PSG.
Neymar is still full of strength and energy to continue as playing football just that injury has been his major setback. Though it's not sure if he'll stay at PSG beyond the summer but I believe that any deal that'll will persuade him to leave must be a deal that's very fair for his football future
