Both teams displayed an interesting game, I think this draw is a score that these two teams deserve. In the second leg later Manchester United will be more favored because they will play a home game. Seeing from their game in this match they played well, even though several players were missing due to injury. This is an opportunity for Manchester United in the second leg and also improve their record against Barcelona.
Even if you think a draw is a fair result for the match but I think one of the two teams deserved to win the match. Manchester United played very well, while Barcelona also had it. Both teams appear to attack making these two teams score goals alternately.
Barcelona had a good chance in the last few minutes of the game, but they had to miss because the ball hit the post. Obviously a draw isn't the best hope of Barcelona or Manchester United, but either way it's good enough for both. In the second leg, I expect a match with the same atmosphere between Manchester United and Barcelona. Both teams have the same chance to qualify, but we just don't know who will step there.
