Flick's decision not to agree to the sale of Fermin was the right one, as Barcelona cannot afford to sell their current players carelessly if they want to strengthen their position next season. The team will undoubtedly feel the impact when a good player leaves, especially if Barcelona cannot then acquire another player of comparable quality to the one they sold. Therefore, not selling Fermin was a good move, and it's clear that Flick has seen the team's intricacies, which is why he immediately disagreed.
Every team is trying to strengthen their squad. But Barcelona is not buying any new players. Barcelona played very well last season. And Hansi Flick wants to create his own match strategy with the same squad. The decision not to sell Fermin is right. Fermin is only 22 years old and a young player with great potential. We saw good performance from Fermin last season. If given enough opportunities, we will see even better performance from Fermin in the future. And this is why Hansi FLick is not willing to sell Fermin right away.
