Former Manchester United captain Gary Neville has taken aim at central defensive pair Harry Maguire and Victor Lindelof.
United were held to a 1-1 draw against relegation-threatened West Brom on Sunday, with the defence coming in for criticism after they lost more ground in the Premier League title race.
Victor Lindelof was singled out for criticism for his role in the Baggies' second-minute opener, after Mbaye Diagne out-muscled him to head home at the Hawthorns.
Neville said, "I want to make a point on Lindelof. Lindelof's problem is Maguire, Maguire's problem is Lindelof.
"I think he (Lindelof) is a really good player by the way, he understands the game, he reads the game, I think he is a good defender. I think if he was alongside a (Rio) Ferdinand or Van Dijk, I think he would make a great pair.
"The problem is he is alongside somebody who isn't the most mobile in Harry Maguire, and I think that is the problem that Lindelof has got. That actually they have invested £80m in Maguire, so they are going to have to put somebody beside him.
"I don't think he does a good job alongside Maguire because they both just drop back a little bit and United need someone to get up the pitch. They have got to get up the pitch, they have got to be more aggressive.
"They have got to have the nerve to make the stomach churn a little bit, that there is a bit too much space in behind them than there ordinarily would be and that is what the best teams have."
