Manchester United are reportedly planning on buying a 'world class' centre-back after it was claimed that players have been privately questioning Harry Maguire's ability.
The Old Trafford skipper has suffered a dismal season and his teammates have noticed his dip in form as the defender comes under scrutiny.
The Times reports that several members of the Red Devils squad don't believe Maguire merits a place in Ralf Rangnick's side as they feel his performances are not meeting the club's high standards.
