DANIEL Giansiracusa will be a "roaring success" as a coach, Western Bulldogs coach Brendan McCartney says.

The 32-year-old will play his 265th and final game against Greater Western Sydney on Sunday, before transitioning into a coaching role at the club.

"It was looking like last year was going to be my last but I probably wasn't ready but I am now," Giansiracusa said at Whitten Oval on Thursday.

"I've enjoyed the opportunity the club has given me to play another 15 games this year but I'm really looking forward to the transition into the next stage of my life."

The forward has donned the green vest for most of his games this season, and has become a mentor for some of the younger players on the sidelines this year.

McCartney confirmed the veteran would be playing the full four quarters against the Giants, and said he had no doubt 'Gia' would develop into a terrific coach.

"He's fulfilling another stage of his life for his family and he'll end up the same as he was as a player," McCartney said.
