"We all knew it was going to be a tough game," he said. "Starting like we did was fantastic for us – not just the goals but we were playing really well.
"I think it took them 20 minutes to cope with us and we were 2-0 up by then and in control. We hit them on the counter-attack and I thought we really controlled the second half.
"Away from home, any clean sheet is massive. Despite all the balls Newcastle put into the box, the back four and keeper were fantastic and fully deserved the clean sheet."
United are currently second in the league table with 15 points from seven matches, four points behind leaders Chelsea.
