Las Palmas and Cadiz are not tough opponents for Barcelona so I think that Xavi not being able to accompany the team during these two matches will not have a big impact, now Brcelona is in top form with high self-confidence and this will make it easier for them when they meet tough opponents. the quality is still below them.
Xavi will only be able to accompany the team during the E Clasicco, this will be very interesting.
