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.
Indeed, Barcelona has to make big improvements with its players, because in my opinion they no longer have experienced players, Barcelona's many young players can become seeds as long as they succeed in showing their best talents, with the new coach now I hope Flick can educate them well until they become players. Barcelona's young people can unleash their talents and bring back Barcelona with a performance that is known to be as good as last seasons. they need a complete overhaul to be able to compete with strong teams next season and of course Flick will do his best to make Barcelona come back.
but I think Barcelona will not be able to compete with Real Madrid, which has strong performance and also has young players whose talent is visible so they can dominate La Liga and the Champions League. Of course, next season I don't think Barcelona will be able to keep up with Real Madrid.
