this is like last season even last season Barcelona were eliminated from the Europa League with an unexpected team, so this season even this season if you look at the Europa League contestants it is very possible for an increasingly fierce competition.
no one guarantees that Barcelona's journey on the Europa League stage will run smoothly and moreover their current performance is not consistent.
There are so many big clubs played in europa league as well. Barcelona lost against frankfurt. Just because barcelona has so many great players and it doesn't mean this club can win the trophy instantly. Barcelona may go out again caused by loosing against the big team. I hope that barcelona will be facing arsenal or MU which are still on fire. It seems like that's gonna be a very interesting match. Barcelona is very inconsistent once it meets the big club.
