Transfer speculation continues to mount as Levi Colwill has been linked in recent days with a move to Barcelona. The defender, currently playing for Chelsea, could add a new dimension to the squad if the rumoured interest turns into an official approach before the end of the transfer window. Barcelona are still pushing to finalise terms. However, Liverpool and Real Madrid are still watching closely and may return with offers of their own. Barcelona's back line has been a real strength this season, conceding just 0.89 goals per game (32 in 36). Levi Colwill would be expected to slot into that unit and hold his own in an already solid setup. Chelsea have also been linked with Bernardo Silva, Cristian Romero and Edmond Tapsoba while Barcelona are reportedly monitoring Rafael Leao, Marc Cucurella and Joao Cancelo.
