“Nate Myles and I did things to each other on the football field, if we got caught for it, we’d be suspended ten to 12 weeks, and that was back when we were playing, let alone today. But we never whinged or complained.

“Our attitude was, ‘what happens out there stays out there’.

Gallen and Myles famously starred in an advertisement encouraging men to talk about mental health following the fight.

“I was only doing what I thought was the best thing for the team, and to try and get the victory. That’s all it was. To be talking about a fight 12 years later, I do cringe.”

One of the toughest men to pull on the Blues jersey, Gallen backed Spencer Leniu, NSW’s latest Origin villain, to embrace the Suncorp Stadium hate, but it was important “not to get caught up in the crap”.

Gallen looked at Leniu and the current Blues inside The Star and told them how much they would love playing under coach Laurie Daley.

Leniu has a Queensland target on his back after his public run-in with Maroons’ legend Johnathan Thurston.

Gallen lost count of the times he was booed and jeered by the northern neighbours, and said if anything it motivated him.

As for any advice for 24-year-old Leniu, Gallen said: “Just don’t get caught up in the crap.

“Remember you’re there to do a job for your team. Pushing and shoving, throwing punches, especially in this day and age, it doesn’t help anyone. Just keep your head.

“For him, he just needs to understand he’s there to do a job for the team. If he does that job we know he can do, he’ll be successful.

“We’ve all got ego, we all want to be the tough guy, but at the end of the day, it’s a team sport, and you need to be there for your team.

“I think he’s got the fastest play-the-ball in the game. He doesn’t have big minutes, but he’s an absolute powerhouse, and the intensity he plays at is through the roof.

“I think as an Origin player coming off the bench, that’s what you need.

“The way they’ve picked this team, with Payne Haas and Mitch Barnett up front, the whole back row can play 80 minutes, [interchange prop] Max King can play big minutes, Spencer just needs to come on to be that wrecking ball ten minutes before half-time, and ten minutes after half-time.

“You could even take him off at half-time and put him on the last ten or 15 minutes of the match. He only needs to play about 25 minutes and rip and tear.

“He’s a pretty scary bloke to have out there for only 25 minutes, going as hard as he can.”
