Barrett’s current deal expires at the end of 2018 with the coach viewed by many clubs as one of the best young mentors in the game.

He took Manly to a six-placed finish in 2017 and their first finals campaign in three years after a dismal 2016 which saw the turnover of 25 players.

The club met with Barrett last week as negotiations continue, while owner Scott Penn told Fox Sports the club was close to signing him until the end of 2020.

Trbojevic says he hopes a deal can be struck to keep the 39-year-old on the Northern Beaches for years to come.   

“(Barrett is) a good coach on the field and off the field he’s a great coach for club culture. I hope they sign him up long-term,” he told Big Sports Breakfast.

“It was disappointing (to drop out of the finals in the first week) but where we’d come from the last few years it was exciting to play finals footy.

“It only makes us more hungry for next year.”

Trbojevic said he and his brother Tom were relishing their Kangaroos World Cup selection  with the pair viewed as long-term Australian players.

“I’m just really enjoying it and any opportunity you get to play for the Kangaroos you take with both hands,” he said.

“It’s going to be a great experience and a real learning curve for me and my brother and we’re just looking to soak up as much as we can.”
