And though Roberts is gearing up for a crucial year with the World Cup just around the corner, he admits he has one eye on the future and a possible return to Cardiff Arms Park.
"Long-term, I'd love to be back in Cardiff at some point, whether that's after this contract or a bit later, I'm not sure," he said.
"There's some great people involved with the club [Blues] at the moment, some great players and some great youngsters coming through.
"I think they're a team on the up with a new coaching set-up, and it would be great to hopefully play a part in their success in future years.
"But I'm not looking beyond this season. It's a massive year for club and country, certainly with the World Cup next year."
