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.
I hope that Las Palmas can trouble Barcelona a little at home, although I don't think that Las Palmas can win at Barcelona's home ground next weekend. But I hope that there will be a little surprise that Las Palmas can bring into their match even though Las Palmas' strength level is still not comparable to Barcelona this season. And on the one hand, Barcelona still has to get more points through the remaining matches because the fight for the runner-up position will continue until now so Barcelona must be aware of this.
