Cristiano Ronaldo has been using Real Madrid’s training base to keep fit after Portugal’s World Cup exit.
After his contract at Manchester United was cancelled last month, Ronaldo is free to join another club on 1 January.
Saudi Arabian club Al-Nassr have made a big-money offer for the 37-year-old forward, although it is understood he has other options.
Ronaldo trained alone at Real’s Valdebebas base and there is no option of a return to the Spanish club.
Ronaldo’s second spell at Manchester United was brought to a premature end after a controversial interview in which the five-time Ballon d’Or winner criticised the club and said he had “no respect” for manager Erik ten Hag.
That came two days before Portugal began their World Cup campaign and Ronaldo started their first three games, reacting angrily when he was substituted in the final group game against South Korea.
The Portuguese Football Federation denied that Ronaldo threatened to leave the squad after being told he would not start the last-16 game against Switzerland, and his replacement Goncalo Ramos went on to score a hat-trick in a 6-1 win.
The tournament in Qatar was expected to be Ronaldo’s last chance to win a World Cup, and he came off the bench against Switzerland and Morocco but could not prevent the African side knocking out Portugal.
