Kylian Mbappe is not distracted by rumours of a possible move to Real Madrid, Paris Saint-Germain coach Mauricio Pochettino insisted on Friday.
The France World Cup-winning superstar has long been linked with an eventual move to Madrid, who courted him as a teenager before he signed for first club Monaco.
His current contract with PSG is due to expire at the end of next season.
The player and PSG are in talks over a possible extension, but Spanish television station Cuatro this week claimed Mbappe wants to move to Real and has decided not to sign a new deal in Paris.
The story was denied by sources close to Mbappe, who spoke to French broadcaster RMC Sport.
"This is something we are accustomed to at the top level, when we talk about big clubs and great players like Kylian, there are always rumours," Pochettino told reporters in a press conference on Friday.
"The most important thing is that Kylian is at peace and is focused on helping the team to achieve its objectives.
"He is so mature despite his youth and both he and the club are focused on trying to reach an agreement so that Kylian stays here for a long time.
"That is what the club wants. We can't control everything that happens outside the club but all that stuff has no impact on the team."
