Paris Saint-Germain coach Laurent Blanc has held clear the air talks with David Luiz over the Brazilian international's refusal to come off against Marseille.

Towards the end of Sunday's game at the Velodrome, Blanc ordered Marquinhos to replace Luiz, who had picked up a thigh injury, only for the defender to refuse to cede his place.

Blanc was visibly upset after the 2-1 win, suggesting drily that "he (Luiz) had done well to stay on the pitch because he was really good in the final ten minutes".

The player and coach met on Monday to discuss the incident.

"Yesterday we had a very good and very long discussion, it was imperative in order to continue to have good relations," Blanc told a press conference on Tuesday.

"It lasted quite some time. I'm quite satisfied with what he had to say at this meeting. It was important for him, for me, and for the team."

Blanc was speaking ahead of Wednesday's French Cup last 16 tie with Lyon for which Luiz remains a doubt.

"He injured his thigh and his knee but he's a special boy," said blanc.

"He'll train this afternoon as usual. He often plays with problems. He turned out (for Chelsea) in the Champions League final with a thigh problem."
