Don't point blaming fingers to Xavi Hernandez, instead follow up the team's board and president that have failed the club, really one of the huge mistakes made by them. Barcelona have been suffering crucial challenges right from time. There's specially no other means of resolving their problems of hefty debts place on the burdens of the team. I'm quite aware of the financial crisis in the club and I must say, it's huge embarrassing to see an elite team like Barcelona not able to sign the prominent players on their Rader, rather they keep making forceful moves that sometime are spotted by FIFA and brings another punishment for them.
Three seasons ago, when Xavi came to Barcelona as their temporary solution, they did not expect him to help them winning La Liga but he did it with them last season. After success in past season, they expect to win Champions League this season and honestly it is not fair for Xavi.
Barcelona play worse than the last season and nearly fail against Real Madrid in La Liga this season but with many young players, many injuries, Xavi did not have best squad for Barcelona to perform best. In addition, young players need time to grow and to strengthen their mentality to deal with pressure. It is easy to sack Xavi but it will not guarantee that a new coach will help them to gain better success. We saw what happened with Barcelona after Enrique, they struggled some seasons before Xavi came and helped them to achieve La Liga title.
