Photos: Cristiano Ronaldo takes part in Man Utd training in preparation for debut

Cristiano Ronaldo took part in his first Manchester United training session after re-joining the club this summer from Juventus.

Ronaldo, who is back at Old Trafford after 12 years away, spent Tuesday at the Carrington training complex with Manchester United boss Ole Gunnar Solskjaer, and then moved on to some drills alongside his new team-mates.

Ronaldo arrived Manchester on Thursday and was required to isolate for five days. But after taking a day two test on Saturday and the day five test on Tuesday, the Portuguese international was able to link up with his new teammates.
