PSG star Neymar is now being linked with a return to Barca.
And Djalminha told Marca: "He's going through a difficult situation, but that's where he must learn from the errors and make decisions. He has to find what the problem is and decide. He was going up in the world, and suddenly he left for a league and a club with less quality and history. Now he must see if it was right or not.
"Only he can think about this professionally. I think that leaving Barcelona was a bad decision."
