The Barcelona team is now most exposed to La Liga. They are currently at the top of La Liga. Barcelona's unfortunate exit from the Champions League. Their main target now is to win the La Liga title, if they fail to win the La Liga title, it will have some adverse effect on their team.
If Barcelona fail to get a trophy in La Liga, Barcelona can still get another trophy this season in the Europa League. However, Barcelona clearly has to focus more on La Liga because they are already at the top of the standings, although not too far from Real Madrid, who are still Barcelona's rivals. Because Real Madrid will certainly focus more on two competitions at the moment and one of them is La Liga. So Barcelona needs to be aware of this if they want a trophy in La Liga this season.
In the Europa League they won't necessarily get a trophy, because even here the competition will be very tight, moreover they have to get rid of Manchester United first to move on to the next round. This is a very difficult thing to do.
Maybe it's true, Real Madrid will focus on 2 more prestigious competitions at once, but as we know that Real madrid is a team that can deal with situations like this with their vast experience.
