Indeed barcelona is currently in a state of pressure because they are playing the second leg at home to manchester united and this has made profits for Erik ten hag and his players. But still the Blaugrana are not an easy opponent for the red devils, I think it is likely that the second leg match will continue into extra time, if one team cannot close the match 90 minutes with a win.
Looking at the bookies odds, you can see that this match is difficult to predict because the odds are all equal with no options to choose from, but I have a good feeling that Barcelona will win this match; statistically, Manchester United does not have a good record of clean sheets against Barcelona, but they drew in their last game, which gives them confidence and hope. Both teams have been in good form recently, but even with the way they performed last time, Barcelona had the game in their hands the entire time. Expect at least 1.5 goals from this match, but Barcelona will win.
