Rumours are swirling around Nayef Aguerd, with Sunderland reportedly showing interest in the defender currently plying his trade at West Ham. With both teams looking to strengthen their squads, the move could have a massive impact on their seasons going forward. Man Utd and Marseille have not withdrawn their interest and could still influence the outcome. Sunderland's back line has been a real strength this season, conceding just 0.86 goals per game (6 in 7). Nayef Aguerd would be expected to slot into that unit and hold his own in an already solid setup. West Ham continue to be linked with Mehdi Taremi, Hayden Hackney and Junior Mwanga while Sunderland are also rumoured to be tracking Issahaku Abdul Fatawu, Cesar Tarrega and Lloyd Kelly.
