Anyone complaining about Xavi is ingrates because the club was nowhere to be found when the guy took over it. The club's dependence on Messi caused a lot of mess for them but Xavi was still able to turn things around. Being number one on the table should mean a lot, and they are with the same performance as their arch-rival Real Madrid, which means they are still doing well. Although they need to be careful now, any mistake or unseriousness could cost them a lot.
IMO, no one is complaining about Xavi's coaching. as football fans, it's normal when we are a little disappointed with the coach when he makes several blunders over the strategy he implements. especially when he didn't make many changes to his squad, I mean in this case when Barcelona was doing their match in the Champions League.
When Xavi Hernandez took over coaching from Ronald Koeman, he brought Barcelona in a better direction. unfortunately, when Xavi was given the opportunity to bring in newcomers, he was unable to bring Barcelona to what President Laporta had hoped for. in fact, Barcelona had to slip up in the Champions League group stage and that was a failure for Xavi with the new squad he had projected.
Next, Xavi still has the chance to win two trophies as he has emphasized on several occasions. however, his mission will be difficult to realize if he doesn't make many changes and if Barcelona fail to win any trophies this season. automatically, Xavi's career will end with Barcelona.
