I agree with you. Gavi is one of the best young players in the world. He was a wonderkid from Spain several years ago. It was very unfortunate when Gavi suffered a long injury which made him miss several important matches. With Gavi's return, I am sure Barcelona will find their best performance again. I can say Gavi will be one of Barcelona's important players next season. I see Gavi has a playing style that is almost the same as Xavi. I'm sure Hansi Flick will include Gavi in the starting XI next season.
Players like Gavi are very important players in order to boost the performance of the Barcelona team which had slumped a bit last season. Because Barcelona still needs to make improvements in their line of players in order to be able to compete fiercely with their eternal rival Real Madrid next season because Real Madrid has also brought in quite talented new players so that La Liga next season will continue to be more interesting for everyone to follow and also by fans of every team there.
