Alan Pardew: "When you have got a natural goalscorer, then you need to create chances and he hasn't been blessed with a lot of chances in the last two games.
"Having said that, we had a run of games here where he had loads of chances and didn't score, and that's how sometimes it goes for a striker.
"We kept saying, 'He keeps getting into position, but not scoring'. This week, he had really and truly, I would say, two really good chances and scored them both.
"Sometimes it's difficult to weigh that up with a player. I do know one thing: his mood, like all strikers, changes with goals.
"I was actually shouting my head off at him about something else before he scored.
"He does a good shift for us as well, apart from the goals."
