Cristiano Ronaldo returned to training on Saturday and will be in the squad for Manchester United’s friendly with Rayo Vallecano at Old Trafford on Sunday.
The Portugal forward wants United to let him leave this summer.
And he missed the club’s pre-season tour to Thailand and Australia for personal reasons.
On Saturday, he posted a photo alongside several young United players showing he was back in training.
“Working in progress,” he wrote, alongside an image of himself with team-mates Charlie McNeill, Amad Diallo, Charlie Savage and Hannibal Mejbri.
Ronaldo, 37, was left out of United’s squad for Saturday’s friendly with Atletico Madrid in Oslo.
But speaking after that match, which United lost 1-0, Ten Hag told reporters: “Tomorrow he will be in the squad. We’ll see how long he can play.”
On Friday, Ronaldo suggested he would face La Liga side Rayo Vallecano.
Commenting on a post by a Ronaldo fan page about him missing the game in Norway, he wrote “Domingo, o rei joga”, which translates as “Sunday, the king plays”.
United said players not in the 21-man travelling squad for the Atletico game – which includes new signings Lisandro Martinez and Christian Eriksen – “will take part in Sunday’s game against Rayo Vallecano, while others are ill or injured”.
Ronaldo met United manager Erik ten Hag on Tuesday and is understood to have reiterated his desire to leave the Old Trafford outfit. He also missed Wednesday’s match against Wrexham that was held behind closed doors.
Ten Hag has previously said Ronaldo is “not for sale” and “in our plans”.
Ronaldo returned to United last season after spells with Real Madrid and Juventus.
