Mallorca was performing so well. I think that barcelona may not be so difficult to win against mallorca but i will not underestimate that team. That team is still worth to be considered as a tough opponent for the barcelona in the upcoming match.
Domination in the ball possession was good but if barcelona will get bad result against mallorca and this will be disappointed to the club
If only Barcelona got into trouble from Mallorca in the match later, then it is likely that in the Champions League it will be much more difficult to get a lot of points. Mallorca may not have shown too many threatening moves so far, but Xavi also needs to realize that even lowly clubs can be dangerous when they are motivated by Barcelona's slump. For that, Xavi as much as possible not to let Mallorca create opportunities to score goals.
We can see how far they can play well without their main players in this match. I agree with what you said, Barcelona's game can be judged by this match before the next game which will put more pressure on them. They don't have much time to prepare who will be starting in the lineup. Xavi should already know who those players are, because most of the players he has retained this season have been his picks.
