"It was very important win and very nice to score a goal," he said.
"I like to be in the box and get to crosses, I had a good touch then it should be goal when you have a good touch.
"It was very aggressive and high pressure, just what I like.
"I’m very pleased today.
"Chris (O'Grady) is a great player to play beside. He’s very strong and he keeps the ball and I go in behind.
