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.
It is true, selling players who are old and no longer have an important role could be Barcelona's choice in the upcoming transfer market. But the problem is, Barcelona currently doesn't have many old players, maybe only Lewandowski, Ter Stegen, Oreul Romeu and Gundogan are old enough. Apart from all that, these four players have a very important role in Barcelona, in essence these four players can be said to be the pillars of Barcelona at the moment. So if, for example, Barcelona sells these players, then Barcelona buys young players, I believe it is very likely that Barcelona's performance will decline much further next season. Because young players definitely need a long adaptation period to be able to unleash their abilities.
Apart from that, what I know is that currently Barcelona has more young players and I think these young players are quite talented. Examples Lamine Yamal, Gavi, Roque, and Joao Felix. All of these players are future assets that Barcelona has, that's why I say Barcelona doesn't need to buy any more players next season. The reason is that currently Barcelona already has quite talented players. So that way, Barcelona can save a little in spending money.
