I also personally think that Barcelona is far ahead of Manchester United in terms of current performance. Barcelona coach Xavi is currently reaping the benefits of his hard work.
The assessment of each person for these two teams is indeed different and that cannot be denied. Because both are big teams in different leagues and obviously have a lot of fans, it is normal for these two teams to have a different assessment. Because Barcelona is also still possible to be defeated by Manchester United in the play-off round match and vice versa. So I personally find it a bit difficult to predict who will be the best among them. Especially in the Europa League play-offs.
The chance is always there. People should remember when Frankfurt was making Barcelona go out of europa league. Barcelona is indeed having very good head to head against MU. that's why bookies were giving small odds as MU is not a favorite team in the upcoming match on europa league.
The match will come very soon and I'm just seeing some changes gonna happen with MU like sabitzer who will be joined in the club as a temporary replacement for Christian eriksen who already faced injury.
I hope that rashford will be making a goal against Barcelona. His contribution is really needed by MU to defeat Barcelona.
