Neville is not impressed with the way the Black Cats went out with a defensive set-up and trying to get a draw.
He said: “I thought Sunderland’s attitude to the game was appalling.
“It is difficult for teams to come to Old Trafford and you don’t expect them to roll over.
“You do expect them to come out and play football and they got what they deserved, I felt.
“And we got what we deserved, which was to win the game and keep our momentum going. It was a very important three points.”
