#1 Manchester United vs Juventus

Juventus is one of two teams to have won all matches domestically this season. They have won all their matches in the league, as well as all their matches in the Champions League so far. They right now have the best chance to win the Champions League (after Barcelona).
With Ronaldo by their side, they have a further advantage over all the other clubs. Ronaldo would be looking forward to his homecoming at Old Trafford, and fans chanting his name for all he did at the club.
For Juventus, this match won't be a big deal, but for Mourinho's side this match could be a shot at redemption. Manchester United has played 11 matches this season, winning only 5 of them, losing 4 matches and drawing 2 matches.
Jose Mourinho has been criticised for most of his time at Manchester United, due to the style of play which focuses more on defending rather than attacking, which is totally against the club's philosophy.
After a miraculous comeback against Newcastle United, fans would be looking forward to see what Mourinho can do to turnaround United's almost disastrous season.
With Ronaldo coming back to his old club, and Mourinho desperate for the win, football fans can't miss this footballing spectacle.
