Manchester United legend Gary Neville says they're "soft". United were shocked 5-3 at Leicester City yesterday.
"Going forward they're a lot better than they have been in the last 12-18months and that's a positive," said Neville.
"But in the first half, every ball that got played forward from distance a Leicester player won it, whether it was the first ball or the second ball. In the second half, a decision goes against them but make no mistake about it they're soft centred.
"There's no doubt Manchester United are soft-centred. They're not tough enough.
"You saw out there today [in the Manchester City versus Chelsea match] that every time a ball went up to Diego Costa - he was getting battered by (Eliaquim) Mangala - and it was the same at the other end with John Terry and Gary Cahill.
"I thought the midfield three for United and the back four got bullied."
