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.
