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.
So far Barcelona is doing well better as they should with the arrival of the date of the clash between premier league side Manchester United. Barcelona shouldn't be taken so highly even if thru have won some of those game lately, it is wrong to think that Manchester United can't hurt Barcelona when it comes to that game. In the area of midfielder's, that's the are Manchester United will definitely use while trying to win that game, once Barcelona's midfielder's can not connect with the attackers the game would be won because they don't have the quality Man United has in midfied.
