Kubo could leave Real Sociedad to sign for Barcelona!

The Barcelona board have begun working on the squad for next season. Joan Laporta and Xavi Hernandez confirmed that, despite the financial issues, there will be new signings in the summer.
Therefore, the Catalans are looking for an attacker who can play as a winger, but also in the middle when needed such as Yannick Carrasco.
However, in the last few hours, 'AS' reports that Barca have become interested in Japanese football Takefusa Kubo, who is shining for Real Sociedad. Kubo used to play for Real Madrid.
The 21 year-old striker has a contract at Sociedad until 2027 and has a buyout clause of 60 million euros. The Basques will only let him leave for more than that amount.
Kubo has been at Barcelona in the past. The former Mallorca man came through the Barca academy after joining them aged 10. However, he had to leave in 2015 after FIFA punished Barcelona for breaking the rules on signing minors.
Madrid were also alert to his movements and got hold of him in 2019, when he turned 18. However, 'Los Blancos' decided to sell him to Real Sociedad, but reserved the right to have re-sign him providing the player agrees and 50% of his rights.
Therefore, everything seems to indicate that there will be a fight between Real Madrid and Barcelona for Kubo's signing. What decision will the Basques make?
