^Looking at previous meetings will not determine the outcome of the match at this point of the season. A lot has changed in both teams after their last meeting. I think if we consider recent forms, we are up for a really interesting game of football because both the teams are on really good form in recent times.
In the past 10 years, Barcelona were stronger than Manchester United and in this season, their difference looks to be very small. If their matches occur in early of season, Barcelona are stronger but now they are similar.
Manchester United where struggling at the start of the season but seems like Erik ten Hag has found his feet and has got the tactic and combination because Manchester United have been winning in the past few weeks and they are on a good winning streak.
After early months with lot of drama and chaos, Manchester United finally find good tactics for their players and successfully resolved drama too. They are now more focusing on training and playing than on fighting with noise from media.
But if I had to predict the score I would say that Barcelona will score 2 goals whereas Manchester will score 1.
Their matches can have a lot of goals if they can make defenders of opponent panic. They have not too strong defense systems which are easily broken especially when they are panic.
