Speaking publicly for the first time since being accused of rape, Cristiano Ronaldo defended himself against the allegation and said Monday he is confident the truth will come out in the case.
But his hero's welcome to the club where he made his name could be overshadowed by the allegation of rape by Kathryn Mayorga after they met in a Las Vegas nightclub in 2009.
Tuesday's clash will be the first time the Italian champions have taken on United in 15 years, while it is only Ronaldo's second competitive club match back at Old Trafford since his move to the Bernabeu.
Cristiano Ronaldo will always be fondly remembered at Old Trafford, but as the five-time Ballon d'Or victor rolls back into town this week, this former hero may be the last sight Manchester United want to see. I play at a fantastic club, I have a fantastic family, I have four kids, I'm healthy. "I don't see how they could lose the Scudetto without self-destructing".
"I have everything, so the rest doesn't interfere.so I'm very, very glad". Of course, I'm not going to lie in this situation, I'm very happy.
"No, I'm happy here", he told reporters in a pre-match press conference. "But, of course, when he returns with a new team he comes to do a job, for them". The most important is I enjoy the football, I enjoy my life.
Ronaldo said: "I know I am an example. However, we can't underestimate our opponents".
One of Cristiano Ronaldo's Juventus teammates has praised the Portuguese following his goal on the weekend, and attributed his class to the years he spent learning from the likes of Paul Scholes at Manchester United.
Ronaldo has so far scored five goals and registered five assists in nine Serie A games.
Let us know in the comments. But we have our weapons.
Juventus proved despite the fanfare surrounding his signing, they remain much more than just Ronaldo by winning both games comfortably anyway to sit top of the group and well-placed for the last 16. He first returned to face his former team in March 2013, for Real, scoring the victor in a 2-1 victory over Sir Alex Ferguson's side.
"It is special for me to return to Manchester", added Ronaldo, who left the Spanish capital for Turin in the summer. "This is a new chapter in my life". (Then-United manager) Sir Alex (Ferguson) is someone I will never forget.
Alexis was absent from the training session ahead of the game with Juventus, and Mourinho says the forward will play no part in the pivotal European encounter.
