It seems that with the squad that Barcelona has now, they will really return to being competitors for Real Madrid. But they still have to make strong chemistry first. Xavi brought a lot of changes to the team, so he has earned the great trust of most people. Xavi had to prove that his movement in the transfer market did make the team solid.
I think Xavi has considered that to make the club he is holding win because when playing a match everything requires good cooperation and is interconnected so it will be easy to get a bond without having to give a lot of their code the players already understand what to do. if a game like that is not created, it will be difficult to get a win because the key to victory in the world of football is cooperation and utilizing the existing players to become a good strategy.
Another advantage of the Barcelona squad is that most of the current players are players who have a high desire to strengthen the team. This can be a motivation in itself for them to do their best. Because if players have a high desire to defend the team, usually they will perform optimally in every match.
