"I had to force the coaches - make their job a bit harder and in their eyes I wasn't doing that so I had a good chat with them in pre-season and they were happy with how I'm training and I've done everything they've asked and this is the reward off the back of it.
"It is hard mentally to stay positive and stay on top of things but it's pleasing to be on this side of things."
The 28-year-old also talked reporters through his try, set up by a huge floated pass from Peter Horne.
"To be fair it was a pretty easy walk-in," he said.
"I was pretty pleased to get out at home and to get a try is pretty pleasing as well.
"I'm just happy to be out there playing. Whoever is in front of me, I'll back myself to play well and I can't wait to get out there for the challenge ahead."
