The Portuguese superstar spent six magnificent seasons at Old Trafford before departing for Real Madrid.
Scores of fans flooded Manchester airport as Ronaldo touched down in familiar territory.
And he needed a large police escort to get through the crowds as one die-hard supporter looked on with a large print of his face on her jumper.
Ronaldo was then whisked to Old Trafford for training, and looked delighted as he strolled around the pitch with his new teammates.
The ace had plenty of highs during his time at the Theatre of Dreams and is sure to be keen to make headlines during the game tomorrow night.
There were fears Ronaldo could miss the crunch game after being sent off in the first group-stage match against Valencia.
However, the Euro 2016 winner was suspended for just one game against Young Boys, meaning the Old Trafford faithful can sing his name throughout the night.
Ronaldo scored 118 goals in 292 appearances for United after joining in 2003 from Sporting Lisbon.
The 33-year-old thrived under Sir Alex Ferguson and ended up winning an incredible three Premier League titles.
Ronaldo picked up the FA Cup during his first season at the club, and played a key role in their 2008 Champions League final win over Chelsea, earning him his first-ever Ballon d'Or win.
His incredible form secured a then-world record £80m move to Real in 2009, where he went on to win four more Champions League titles and four more Ballon d'Ors before joining Juventus last summer.
