Barcelona will be a very tough opponent for Manchester United, because currently Barcelona leads the top of the La Liga standings and Manchester United is in 4th place in the EPL.
I don't think matches can be measured by standings. especially in the Europa League. those who look strong can also cry because they lost to a weak team.
Barcelona vs MU match is the concern of many fans. this is sure to be an interesting match, Barca also still hasn't returned to their best form after the break. the situation in La Liga is also bad because Madrid is ready to chase them.
while MU might be under pressure in the match later. Barca is very strong in midfield, and MU is still struggling with their attack line. predicting this fight is still quite difficult.
