4. Man United vs. Barcelona (Bracket B):

Ole Gunnar Solskjær said he'd prefer to play the 2nd leg away. He believes that if his team gets a good result at home, then they can go to the Camp Nou and beat Barcelona just like they did with PSG. His confidence in his players is commendable, but Barcelona is no PSG.
The only other player on this planet who is capable of winning the game all by himself is on a mission to bring back the UCL to Barcelona. At least that's what he promised the Barcelona fans at the start of the season, and that's what he's been working hard towards. There is also the bitter fact that Barca were eliminated in the quarter finals in every year that Real Madrid won, rewriting history and making records with their treble of UCLs.
This season, the winner will be determined by who wants the trophy most, and who is willing to work hardest for it. The tactics, the talent and skills of the players will all be secondary, the deciding factor will be the burning desire to not just to play a good game, in every game, but to win the whole competition and to celebrate with their fans at the end of the season. There are few that can compare to Ronaldo and Messi in this aspect. They have won 10 Ballon d'Ors and 9 UCLs between them, yet neither seems like they are even thinking of slowing down.
Team to progress: Barcelona
