^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.
@Lordhermes if they come against Roma then they’ll definitely perish, because Mourinho is a serial winner and Arteta side yet doesn’t have the experience of winning a big trophy hence too early to predict for Arsenal’s success. @zaki12 I’m not sure if Manchester United is a opponent to be feared, because if they play McFred and perform like their opening game then they’ll be easily beaten, but I’m sincerely hoping that they can transform themselves quickly and then compete for all the trophies.
Mourinho can fail to help his clubs (not rich clubs) to win their national leagues because there are more challenges than the past with big difference from rich clubs and non rich clubs.
However in cup format like Conference League, Europa League or Champions League, Mourinho can win it with his teams. He did it with Porto, Manchester United and Roma in 2021 - 2022 season with a trophy in Conference League.
With Cup format, Mourinho won't have to think too far and he focuses on each match. With his tactics, if players do his idea well and with luckiness, they can win each knock-out round and go the final match.
