Barcelona has ensured its ticket to the Europa League. but yes, we agree. there is no guarantee, Xavi Hernandez's team can walk smoothly to the final match later. to be sure, there are other formidable teams here that have existed before. I am still optimistic, Arsenal will remain a strong contender in this competition.
Obviously Arsenal will be strong competitors in the Europa League, besides that there are also other teams such as Freiburg, Lazio, PSV and Manchester United who will give fierce resistance in every match which of course for every team in the Europa League this season. Barcelona have to fight a little harder in the Europa League because I see Barcelona's performance at this time starting to decline a bit, while the teams in the Europa League are still in better shape.
Arsenal might be will considers as strong competitors because they were passed group stage with good performance but if we see from history sides Arsenal is lack of trophies for european competitions so this is big challenge for Arteta to bringing first trophy for Arsenal and it won't be easy because Europa league is the places for mediocre teams who can eliminate big teams
Europa league this season is quite different because there are plenty of big teams who joined because of eliminated on champion league such as Barcelona, Sevilla, Ajax or maybe Juventus so the competitions between these teams will be so tight and it's hard to predict who will be the winner of Europa league this season because most of them have equal chances to get the trophy
