Jack Ginnivan says it’s a dream come true to “finally don the brown and gold” after the Collingwood premiership winner had his first day at Hawthorn following his shock move during the AFL trade period.

A Hawks supporter as a kid, Ginnivan’s request for a trade to the club just two weeks after winning a premiership with the Magpies came as a shock to the AFL world.

But the 20-year-old small forward declared he couldn‘t be happier after meeting some of his childhood heroes including coach Sam Mitchell and putting on the jersey for the first time as a player.

“It’s a dream come true to don the brown and gold finally. I used to barrack for them obviously,” Ginnivan said.

“One of my favourite players was Sam (Mitchell), growing up watching him, having his number on my back, they are things you dream of as a little kid and for this to happen is so special.”

Ginnivan also said he “copied” the goal-kicking routine of veteran Hawks forward Luke Breust who he will now get to play alongside.

“It’s going to be pretty cool, Luke Breust is one of my idols … I always wanted to play like him an I coped his goal kicking routine and things like that. ,” he said.

“It will be good to stand next to him.”

Ginnivan said it had been a “crazy” few days after deciding to leave his premiership teammates behind but was lured to the Hawks by his childhood links, and the excitement of the team he thinks they can be.

“I think the young core as well, the excitement the boys play with, they are always fast and moving the ball forward, people like CJ (Changkuoth Jiath) and Dylan Moore, they are so exciting to watch,” he said.

Ginnivan made the move having struggled to cement his place as a regular at the Magpies this year and with the arrival of Lachie Schultz from Fremantle giving Collingwood another small forward to choose from.

The Hawks also lured back three-time premiership forward Jack Gunston from Brisbane to bolster their forward stocks and work as a mentor to Ginnivan.
