Kylian Mbappe has been put up for sale by Paris Saint-Germain after he was left out of the French club's pre-season tour to Japan and South Korea.
Mbappe refused to sign an extension for the remaining one year of his PSG contract and the club had been determined to stop the 24-year-old from leaving for free at the end of the upcoming season.
As per Sky Sports, PSG are convinced the French footballer is set to join Spanish football club Real Madrid on a free transfer next summer which the club has perceived as a betrayal. The star footballer had earlier said that he would not leave the Ligue 1 club for free.
Real Madrid are favourites to sign Mbappe, which would end the France international's six-year stay at Parc des Princes.
