He told the club's official website: "It's a massive three points. The first goal was the most vital one of the game and I was in the right place at the right time to get something on it.
"It wasn't easy today, but we went out and did our jobs. Our performances over the last few weeks and again today have showed what we can do.
"We're creating chances, doing well and fighting and I think that showed today."
The Black Cats are 17th in the Premier League, but are only outside the drop zone on goal difference.
