"I think I would probably put the [win] down to the team work and character. Central were on attack quite a lot of the time. At one stage, we had about seven minutes on our own line and didn't concede a try."
He said the fitness really showed towards the end of the game when they ran in three tries in the last 12 minutes.
"It was quite close up until then."
He said they had been working hard on their fitness during pre-season, so it was good to see it pay off.
