There is no doubt we are having impressive work by the Xavi Hernandez in during last 30 months even their sources are limited but still he is doing his best for having better results and keep things at the top level and now having news of he is going to stay for more time going to have positive impact on the teams performance and fans as well which was looking not good after his announcement leaving at the end of the season.
Xavi departure will have a bad impact on the coming season because we never know whether a coach who has intelligence like Xavi will manage the existing players well without being able to bring in quality players like other teams.
persisting to stay with Barcelona is also one of the bad things for the achievements that the coach will get because being with Barcelona for too long will certainly not give you more experience.
I can't imagine what Barcelona will be like in the coming season without Xavi and it will definitely look very bad and the fans will definitely be very worried.
