Gary Neville has told Manchester United manager Erik ten Hag that his side has "got a big problem" at centre-back, after Casemiro played alongside Victor Lindelof in a make-shift defence during their 2-0 Carabao Cup win over Burnley.
Ten Hag oversaw his side's first competitive fixture in more than a month on Wednesday night, as United won in front of their home fans to progress to the quarter-finals of the EFL Cup.
With both Raphael Varane and Lisandro Martinez taking part in the World Cup final on Sunday, the clash with the Clarets came too soon for the pair. Harry Maguire's illness prompted Ten Hag to deploy Casemiro alongisde Lindelof in the centre of United's defence.
