On the back of the huge win for lowly Newcastle, Lascelles has questioned the ability of Man United defenders Phil Jones and Chris Smalling on the ball, with both players struggling throughout at St James' Park.
"First half, they were making a lot of mistakes, giving the ball away," he told reporters at full time. "I think it was down to our pressing, being aggressive and on the front foot. And obviously, they didn't like it.
"I could see their centre-halves on the ball, and didn't know what to do with it. I don't think they were at it from the start. A lot of their players were missing.
"I don't think United turned up today. When you play against Arsenal and Manchester City, you can really see their quality. One mistake or a lack of concentration, and a goal will go in. Today, we just wanted it a lot more."
