Newcastle manager Rafael Benitez was frustrated at half-time, with a score-line that hardly matched the performance.
But, rather than making changes that were "like for like", he changed the whole system, to win the three points.
Newcastle manager Rafael Benitez, speaking to Match of the Day: "We didn't deserve to be losing 2-0 but you have to react and at half-time we talked about staying calm - it was really difficult to keep the players calm but they understood that that was the way.
"To concede one minute after missing a penalty is the worst nightmare for any manager but we reacted well. The players were pushing and pushing and they had the belief and confidence we could do it.
"We have more confidence but we have to keep winning."
