Because if, for example, Barcelona sells several of its players next season, in my opinion that is also too risky. Because, the risk is that Barcelona will not necessarily get better players than the current players. So in my opinion, utilizing existing players is a way out of the problems Barcelona is currently experiencing.
There are several players whose performance may decline due to age and I think those who are old enough can be sold and bought new players, at least young players who have more ability and have the potential to be able to play in the main squad at Barcelona, after all the competition is very tight in Next season, if we continue to play experienced players, it won't be enough because stamina and performance are necessary, especially since league matches are also quite time-consuming, having young players will be good enough to maintain consistency.
But I don't know whether Barcelona has enough money to buy new players and sell their players, even though we know they are in a financial crisis, I am not a Barcelona supporter but what I see is that Barcelona should have lots of young players to fill the main squad so they can compete in the season. in the future and Xavi can rotate each of his players so that he can continue to maintain consistency next season, at least winning the Laliga title is already a good achievement, let alone the UCL which is certainly not an easy competition to overcome.
A team needs experienced players in several sectors but they also have to be able to combine with young players and so far we have seen that the Barcelona team has failed to be able to create a squad that combines senior and young players like Real Madrid has done.
Barcelona needs quality players and if they want to compete again for the title and compete fiercely on the European stage, there are many lines that Barcelona management needs to improve to create a capable squad, but with all the internal problems that this team is experiencing, all of that is not possible. it will be easy and in fact I think it will take a long time for Barcelona to recover, I don't have much hope for Barcelona to be able to compete with Real Madrid next season.
