Cristiano Ronaldo is due to meet Manchester United manager Erik ten Hag on Tuesday to discuss his future at the club.
He has yet to train with the squad but has now flown back to Manchester.
Ten Hag has previously said Ronaldo is "not for sale" and "in our plans."
Ronaldo returned to United last season after playing for Real Madrid and Juventus.
Ten Hag said he spoke to Ronaldo before the tour, explaining: "I had a good talk. That is between Cristiano and me. What I can confirm is we had a really good conversation together.
