The La Liga giants reportedly made the offer on Sunday August 21, and Paris Saint-Germain are yet to respond to their proposal.

Mbappe is out of contract at the Parc des Princes next summer and he has so far refused to sign a new deal, despite PSG's attempts to get the France international to commit his future to the club.

The 22-year-old has told PSG that his dream is to play for Real Madrid, who have been linked with a move for the World Cup winner throughout the summer transfer window.

Mbappe has scored 133 times and made 63 assists in 174 games for PSG in all competitions and has helped them towards 11 major domestic honours, including three Ligue 1 titles.

He arrived from Monaco on an initial season-long loan in 2017 and was signed permanently for £165.7m a year later.
