The brother of Marquinhos admits he could quit PSG.

Marquinhos' brother and representative Luan says he could push to leave.

"Marquinhos has always been exemplary with the club - he's never complained," Luan explained in an interview with L'Equipe.

"He has however often been a spectator during big matches… we were clear Marquinhos is going to play at the Olympics.

"Until now, we've been cooperative. But it can no longer continue like that otherwise we're going to enter into a conflict. Our patience has limits.

"We like the club, the supporters, but they also have to show us a minimum of respect or else he's going to have to leave PSG."

L'Equipe say Luan then listed the clubs that have shown interest in Marquinhos, claiming Barcelona, Arsenal, Chelsea and Manchester United have all made enquiries.
