Greenwood joined the Gold Coast Titans from the start of 2017 from St Helens and made 22 appearances in his debut season.

But after Neil Henry left the Titans and Garth Brennan took over, the forward was frozen out and did not make a single NRL appearance this season.

In June he left Gold Coast and signed with Super League side Wigan, and today his new side faces Warrington in the Super League grand final.

"My first year I couldn’t thank Neil enough for the work he put into me," Greenwood told Inside Sport.

"He brought me over, and then Garth didn’t like the way I played. I just had to move on. I keep in touch with Neil still, we texted the other day. He just wished me all the best. I was playing in the Queensland Cup with Burleigh, it was still tough. It’s a good competition.

"I enjoyed it, but you want to be out there [in the NRL]. You want to be in the limelight career-wise as it’s a short career, 10 to 15 years and then your retired. So you want to look back and know you’ve taken the opportunity.

"And to get that opportunity to come to Wigan was a no-brainer."

Greenwood has no hard feelings about his abrupt exit from the Queensland club.

"That’s sport at the end of the day," he said.

"You just have to move on. I’ve moved on. It's worked well. I’ve had to pinch myself at times, have a reality check at times. To be in the grand final is just phenomenal."

The 25-year-old hasn't ruled out a return to the NRL one day.

"Maybe. I take each week as it comes," he admitted.

"But I'm loving every minute of it at Wigan."

First of all he has the small matter of a grand final to win. Four years ago Greenwood was part of the St Helens side, but did not get on the field, that won the Super League decider.

Now he is relishing his chance to take the field at Old Trafford.

"This is my first grand final," the back-rower said.

"I was 18th man [in 2014] and I just wanted to be a part of it. I’ve still got the winner’s ring but it felt a bit hollow… it’s hard to explain. You want to feel like you’ve contributed to. If we win on Saturday that will even better. Hopefully we can do it."
