PSG defender Marquinhos has paid a glowing tribute to Chelsea defender David Luiz.
The two Brazilians became close during their time together in Paris.
And Marquinhos is backing Luiz to prove himself again after his return to the Chelsea first team this week against Qarabag.
"David Luiz? He was really a champion, he came from Chelsea, with a Champions League won, with a lot of titles, and he came here," Marquinhos told Goal.
"He really brought a winning mind, with a very interesting joie de vivre. He was someone who brought us joy in the locker room and on the field."
