Do Barcelona need neymar?

For weeks or months if I am correct, there have been fuelled rumours going on about neymar planning to return back to Barcelona

Actually neymar is a great player if not one of the best player after c.Ronaldo and messi.

But looking at his new lifestyle, his reaction towards some situation and his injury issue. I don't think it will be a good thing for Barcelona to bring him back to the club.

I want to hear your opinion about it.
Is neymar worth coming back to Barcelona?
