The talented French central defender is at the center of the technical secretariat's planning to enhance local defensive rotation. The offensive move is in response to a specific request from the German strategist, who has asked for a significant financial effort from the presidency. Barcelona is pursuing several important signings in this summer market.
Conversations with the Bundesliga team and the player's agents are progressing positively to finalize an appropriate financial package. The intervention of the Barça executives drastically alters the plans of Arsenal, the British squad that had been monitoring intensely.

The formal valuation of the young French talent approaches a fixed €60 million at the offices of the German club. The upcoming weeks will be crucial in determining if the intentions can converge into a landmark signing for the Spanish tournament.
Barcelona assumes absolute protagonism in the summer holiday window, determined to present the essential sporting arguments in the financial discussions. The higher-ups intend to expedite the pending bureaucratic procedures to provide their new coaching staff with a fully guaranteed asset.

Barcelona envisions the French international as the perfect partner to accompany young academy player Pau Cubarsí for the next decade. Scouting reports strongly recommend meeting the required amounts to secure the defense against future demands.
