CR7 completed his move from Juventus on 31 August and reported for national-team duty with Portugal: typically, he scored twice in a World Cup qualifying win over Republic of Ireland to become the record scorer at international level.
A suspension picked up in that match meant Ronaldo was granted permission to leave the Portuguese camp last Thursday night and fly to Manchester, in preparation for his much-anticipated second spell at Old Trafford.
Cristiano reported to Carrington earlier today and, after spending time with Ole Gunnar Solskjaer in his office, he joined his team-mates on the training pitch.
