Harry Maguire and Victor Lindelof are facing an uncertain future at Manchester United after failing to impress during Erik ten Hag's first season in charge.
Ten Hag made signing a centre-back a priority after moving to Old Trafford from Ajax and promptly authorised a £55million raid on his former club for Lisandro Martinez, who has taken Maguire's spot in the team for the majority of the campaign.
Former Real Madrid defender Raphael Varane has partnered Martinez more often than not at the heart of United's defence, however, injuries to both has seen Maguire and Lindelof come in from the cold recently.
