The Brazil international paid tribute to his coach as the Portuguese prepares to bid farewell to the Spanish giants
The former Inter boss will leave Spanish football in the coming weeks after three years with the capital club, and the Brazilian says he can do so with his head held high.
"We have not yet said goodbye to Mourinho in the locker room, but he is a great coach who has helped Real Madrid a lot," he told Canal+.
"I wish him all the happiness in the world. We'll see who his replacement is and we'll see what happens next season."
Neymar's long-awaited move to Barcelona was confirmed on Sunday and Marcelo went on to welcome his fellow Selecao star to Spain.
"I'm happy for him because he's going forward in his career. I wish him all the best," he said.
