Basically, about Xavi being willing to stay as Barcelona's head coach is not about being good for fans, but good for Barcelona's own finances . Because of course, if Xavi leaves then Barcelona will also spend a lot of money again to recruit a new coach. Because after all, at the same time Barcelona still needs to buy some players which of course Barcelona will still spend money in the transfer window later . Therefore, Xavi's stay clearly makes Barcelona's finances may remain a little good, but the news that Xavi chose to stay I am sure has nothing to do with fans, because fans also cannot do anything to make Xavi stay or leave.
Negotiations only involved club management and Xavi, fans were not involved in it at all. The agreement between both parties means that Xavi will extend his tenure as Barcelona coach next season. This agreement will certainly be very beneficial for Barcelona. This season's failure can be evaluated next season, Xavi certainly has several plans to face the heat of competition in different competitions next season.
Reshuffling the team is Xavi main focus, perhaps there will be several players who will be released to other clubs and there will also be quality players brought in. Xavi will try to provide something new for Barcelona next season that can entertain his fans. Winning the La Liga trophy and also the Champions League is still Xavi target with Barcelona.
