Barcelona's performance in the previous season in La Liga was very consistent and they won the title. The main reason for this was that in the previous season the focus of the Barcelona team was only on La Liga matches. We have not seen Barcelona players play well in the Champions League and Europa League. They only focused on La Liga so the team was able to win the title by consistently performing well.
This season's scenario is different. Barcelona also wants to play well in the Champions League. This is why Barcelona has fallen behind in the title race by performing poorly in several matches in La Liga. Barcelona's performance is also somewhat erratic now due to the busy schedule. But I would say Barcelona have the potential to do well in the Champions League.
It makes sense, Xavi has an obligation to balance his squad in the La Liga and Champions League competitions. The busy match schedule is one of the biggest challenges for Xavi, because on the other hand, several key players being injured is also a problem that must be found for a solution. The potential for a revival in the future is quite open, especially if Xavi gets budget support from management to hunt for players in the transfer window, I think releasing young players and recruiting more experienced players is the best option.
Barcelona will face Napoli in the round of 16. The first leg will be played at Napoli headquarters. I don't think it's an exaggeration to put Barcelona ahead, because we know Napoli is also in an unstable condition too. The change of coach has not been able to make the performance of Osimhen and his colleagues consistent, this is a favorable situation for Xavi in his efforts to bring Barcelona to the quarter finals by beating Napoli.
