I think too this match is 50-50%. Both teams are considered equal in terms of squad quality as well as strong teams in their league. It will be a matchup like the early final of the European league. We are lucky that we will have the chance to watch this match twice. Manchester United must make a difference at home because it is very difficult in Spain.
The first leg will take place at Old Trafford, Manchester United must take advantage of opportunities when Barcelona travel to their headquarters, because when they travel to Camp Nou it will be difficult to develop a game.
If you count Head to Head in the Champions League, Barcelona is superior to Manchester United.
Both teams have the same chance to qualify for the next round, Barcelona is relying on a young squad this season, under Xavi's coaching many young players have developed so much, but in terms of experience maybe Manchester United is slightly superior.
