Former Manchester United defender Phil Neville labelled Phil Jones and Chris Smalling "a disaster" after the Red Devils' defeat to Newcastle.
Neville, speaking on Match of the Day 2, analysed the pair's all-round display at St James' Park after Rafa Benitez's side beat the Reds 1-0 thanks to a Matt Ritchie strike.
"They have got the best defensive record because they have the best goalkeeper in the world in David De Gea and [Nemanja] Matic out in front who protects them really well," Neville said.
"But the last two away games [against Tottenham and Newcastle], Smalling and Jones have been a disaster.
"Against Dele Alli and Harry Kane, they got bullied."
Neville added: "Against Newcastle did they make many mistakes, no, but they created a nervousness and a tension.
"They were making decision that were strange. They were making decisions all day where you were thinking, 'what are you doing?'
"They brought these two as the best young centre backs in England."
