Having impressed in the NRL with Gold Coast, Roberts decided to make the big move to the UK to start his career in Super League with Warrington.
The 26-year-old is looking forward to the new challenge and says Price was a big factor behind him signing a three-year deal at the Halliwell Jones Stadium.
He told League Express: “I said to myself that last year was the best year of my career football-wise. But it’s not about the footy at times, it’s about the respect you get from a club, and Steve and Warrington certainly made me feel wanted.
“As a player you want to be respected and wanted, and they gave me and my family the opportunity to experience England and Super League. It doesn’t matter who I’m playing for, I just want to be happy.
“Once I’d made the decision, I spoke with Steve and he gave me the rundown of the club and where he wanted it to go. He respected me as a person and a player, he’s seen me play and he knows I can play, and I look forward to linking up with him over here.”
