Paris Saint-Germain defender Marquinhos admits he feels flattered by Barcelona's reported interest in signing him, but believes his current club will not allow him to leave.
Barcelona have long been credited with an interest in snapping up the Brazil international and are believed to be keen to lure him to Camp Nou as they continue to rebuild their defence.
The Catalans have already added Lucas Digne and Samuel Umtiti during the summer but the 22-year-old does not expect to follow in their footsteps, as "PSG are not a selling club".
"I am happy that a big club like Barcelona are interested in signing me," Marquinhos told France Football.
"I cannot deny that. We are talking about the biggest club in the world here.
"But I have to keep my feet firmly on the ground because PSG have never been open to selling me. We will see what happens.
"Is the door out of PSG open? No, not really."
Marquinhos has a contract with the Ligue 1 champions until June 2019.
