Manchester United legend Paul Scholes believes manager Erik ten Hag cannot trust some of his defenders.
The Red Devils have been using makeshift back fours throughout this season, partially due to injury.
After their 4-3 Champions League loss to FC Copenhagen, Scholes admitted that Ten Hag has turned to Harry Maguire and Jonny Evans for their ball-playing abilities more than anything else.
The duo are starting ahead of Raphael Varane, a World Cup and four times Champions League winner.
I actually think he's playing Maguire and Evans at centre-half because he thinks they're the two best ball-playing centre-halves," the former United midfielder told TNT Sports.
Which in itself is a bit of a worry."
How can he [ten Hag] pick a settled back four?" Scholes added.
We saw Varane play against Galatasaray and he was all over the place.
Even Casemiro when he played he looked a bit loose and not playing his position well.
These are two players who have won the European Cup five times [Varane has won it on four occasions], if you can't rely on these type of players, where do you go?
You can see where he's gone, back to Jonny Evans who was a free transfer!"
