After recruiting three attackers during the last winter transfer window (Ferran #torres, Adama #traoré and Pierre-Emerik #aubameyang), FC Barcelona would like to review a large part of their defense. The club would be interested in four defenders for next season. According to the Catalan media Mundo Deportivo, the club chaired by Joan #laporta is monitoring the situations of Noussair #mazraoui, Andreas #christensen, Cezar #azpilicueta and José #gaya very closely. The first three are out of contract next June and are already free to commit where they wish, while José Gaya is linked with Valencia until 2023.
