Manchester United icon Cristiano Ronaldo has returned to training with Saudi Pro League side Al Nassr following the culmination of the winter break.

The 39-year-old will be out of contract at the end of the season and speculation over his future has increased in recent weeks. It has been rumoured that Paris Saint-Germain could be a possible destination with Ronaldo claimed to be 'open to the idea of a new challenge'.

However, transfer expert Fabrizio Romano has dismissed those claims. "Paris Saint-Germain are not in talks to sign Cristiano Ronaldo despite reports. Discussions not even taking place now," he said.

Amid the rumours, Ronaldo has sent a strong message on X (formerly Twitter). Sharing some pictures of himself back in training with his club, he wrote: "Back to work."

Ronaldo has also made his thoughts perfectly clear on both the Saudi Pro League and Ligue 1 during the Globe Soccer Awards last month. He said: "Saudi League is better than Ligue 1, of course. France only has PSG. The rest are finished.

"Try to sprint in 38, 39, 40 degree weather and see... To be honest I think the Saudi League is not worse than French league, in my opinion. In [the] French league I think you have two, three teams with a good level.

"In Saudi now I think it's more competitive. They can say whatever they want, it's just my opinion and I played there one year so I know what I'm talking about. But I think right now we are better than [the] French league, we still improve.

"We have very good teams, very good Arab players, but the infrastructure - they need to improve a little bit more. Even the referees, the VAR system, should be a little quicker. But I'm happy here, I want to continue here, I will continue here."
