  "We should have had the game won before that and we made it harder than it should have been.
  "It was about time I hit the net. I had to make the run because you know a player of Niall Quinn's quality will deliver the ball.
  "Andrew Waterworth is just a natural goalscorer and he gave us the edge in the first half."
