Two big champions league clubs who have had a tough time in some years now and unfortunately have to face each other in the Europa league and not in the champions league. For many people the both of them may have the same chances of qualifying, but i feel manchester united will beat barcelona, i think amongst the two teams they are the one in a better position and form at the moment, Erik ten hag is doing very well in his new team and the Europa league is one of the trophies he may win. Manchester united started the season in the Europa league so they will play better than barcelona who started in the champions league and were hurt and disappointed to be eliminated from the champions league down to the Europa league, surely it will affect their performance against manchester united.
