If they play the same way they did against sevilla they have a huge chance to win as we can see there are some improvements with xavi but i think thats the best he can do right now considering the squad he has not to mention the inexperience aspect but i am confident that they can win against mallorca even if that it wont be an easy task.
Fans' confidence in the performance of Barca now has really decreased drastically, even a few have predicted that Mallorca will provide a formidable resistance to Barca in the match later
xavi has a tough test and demands from the fans, he will definitely get through this. I heard news that Xavi will encourage young players like Fati and Pedri to play more, hopefully that's a good solution
Not any option for Xavi except playing with young player and fans need patience for progress at the future, most needed by Barcelona right now is fans can watch on stadium with full capacity and ticket sold out to help financial, but many fans less hope right now after Messi left club and almost as home match ticket not sold out. La Liga have rule where club can't get capital stock full 100% by foreigner and only local people can get all it, I think why Barcelona still faced with crisis financial not any investor have chance to buy Barcelona as their club like primer league for Manchester City.
