Pau Cubarsi, currently with Barcelona, is the latest name linked with a potential switch to Arsenal. The defender could become a key signing should the move materialise, as the club seeks to strengthen in a key area of the pitch. Talks are underway, and with no competition emerging, Arsenal are seen as the sole contenders for the player's signature. Arsenal's back line has been a real strength this season, conceding just 0.71 goals per game (22 in 31). Pau Cubarsi would be expected to slot into that unit and hold his own in an already solid setup. Barcelona continue to be linked with Nicolo Tresoldi, Alessandro Bastoni and Julian Brandt while Arsenal are also rumoured to be tracking Caleb Marfo Yirenkyi, Rodrigo Mora and Lewis Hall.
