There is no need to compare now Real Madrid, which had the opportunity to strengthen the team in the summer, and Barcelona, which spent the entire season without new transfers and, in addition, some important players, like Dembele, left the team.
Real Madrid's financial situation is much better, so they look better this season, Barcelona in a sense is trying to survive, I'm talking about finances, and in such conditions putting pressure on Xavi was a mistake. I’m almost sure that without Xavi it will be even more difficult for Barcelona, but now nothing can be done, they need to look for a way out of this situation.
Real Madrid has better financial current condition than Barcelona after facing financial crisis more than last several season but Xavi Hernandez success won La Liga tittle last season. I agree with you how Barcelona's management putting Xavi Hernandez on huge pressure without giving much money for signing new players and management huge expected with Barcelona winning La Liga and UEFA Champion League tittle. Its main problem not comparison between how much money spending by management and their target keep impressive performance make Xavi Hernandez announced for leaving Barcelona next season.
I don't know for next manager will be success like Xavi without get much money for signing players but management huge target for winning La Liga trophy.
Barcelona without doubt have been having financial crisis in recent years which has prevented them from making major signings at the club but that hasn't stopped Xavi Hernandez from delivering great performances at the club since he was appointed as the club manager. As recent as last season, he helped the club to win the Spanish La Liga title and have also been impressive this season as he's lead them to the quarter finals of the UEFA Champions League competition as well making sure they stay in the second position of the league table. I've never read any report that suggests that Barcelona's management is putting any sort of pressure on their manager rather it's Xavi Hernandez that wants to leave the club at the end of the current season. The problem at the club now is that should Xavi Hernandez leave the club at the end of the season, can they get a manager that'll replace him?that I think will be very difficult for them
