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.
There are also many strong competitors in the Europa League, so, although Barcelona may be one of the candidates, this doesn't guarantee that they will be the champion. It is not easy to defeat many competitors there. Xavi needs to make certain strategies that will be more effective in fighting every team in Europe League. Moreover like Arsenal, Lazio, Juventus, Man United, and others.
Earlier in the season it looks as if Barcelona was targeting to win the laliga, that made them not to put too much seriousness with the Champions league , coming to the europa league it won't be easy for Barcelona because their are tough teams in the Europa League that are very consistent in the europa league. I know Barcelona won't be below average in their performance.
