"It was an important result because Newcastle were a very determined team, very, very difficult to break down," he told Sky Sports. "We stepped up our passing in the second half and played with increased pace, which we needed to do because we were far too slow in the first half.
"Newcastle had a lot of pressure in the first half and one or two dangerous moments in our penalty box, but we created chances - although it is about taking them.
"But once we got in front, I was quite confident."
