Cristiano Ronaldo and Jorge Mendes pictured at Carrington for Manchester United talks with Erik ten Hag

Cristiano Ronaldo has been pictured arriving back at Carrington with his agent Jorge Mendes ahead of talks with Erik ten Hag about his future at Manchester United.

Ronaldo, 37, has yet to join up with United since Ten Hag began work as first-team manager, and he missed the entirety of their recent pre-season tour to Thailand and Australia.

The former Real Madrid star was expected to be at Carrington with the rest of United's international participants on July 4 but remained in Portugal, citing a family issue, and missed four friendlies in Bangkok, Melbourne and Perth.

Sir Alex Ferguson was also pictured arriving at Carrington this morning.

Two days prior to Ronaldo's scheduled return, it emerged he wanted to leave United due to their slow movement in the transfer market and failure to qualify for the Champions League, which has slashed his salary by 25%.

It is understood that the Portuguese forward arrived back in Manchester on Monday ahead of talks with Ten Hag about his future as the two parties look to come to an agreement.

United have regularly reiterated that Ronaldo is not for sale this summer, with sources insisting that he still has a key role to play as he enters the final year of his contract at the club.

Ten Hag has indicated already that Ronaldo will not start the season against Brighton on August 7 if he is available for selection as he will have had less than two weeks' training with teammates.

Speaking in Perth last Friday, the new United manager was unable to specify when Ronaldo was likely to be back in training, but reiterated he was planning to keep him at the club.

"I focus on the players who are there. They are doing really well.
