Real Madrid have made a £137m (€160m) bid to sign Kylian Mbappe from Paris Saint-Germain.
The La Liga club made the offer on Sunday 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.
Ronaldo is also out of contract next summer and has not told Juventus he wants to leave, but the Serie A club would not stand in his way if another club comes in for him.
Real Madrid, who have incurred an estimated £257m (€300m) in losses due to the coronavirus pandemic, signed David Alaba on a free transfer earlier this summer after his deal at Bayern Munich expired, who is the only addition to their squad so far this summer.
Meanwhile, PSG pulled off the sensational signing of Lionel Messi earlier in August, while Achraf Hakimi, Sergio Ramos, Gianluigi Donnarumma, and Georginio Wijnaldum linked up with Mauricio Pochettino’s squad earlier in the window.
