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.
To be sure, at least Barcelona need a little time to analyze some of the toughest opponents they will face in the Europa League, because this is definitely different from the Champions League.
The decision to change strategy I think it depends on the situation, and xavi definitely knows better what his team needs at the moment
Welcome for Barcelona in the Europa League. To be honest I'm a bit doubtful that Barca can last long here
