He then spent time at Avondale Heights and Spotswood, known as the Woodsmen, where he played alongside fellow Roos' recruit Jason Marks.

"Jason was a big influence and Peter German also coached me at Williamstown, I like the way he goes about it," Nastasi said.

Roos' coach German will joins Marks, Nastasi and ex-Mt Eliza's Kyle Docherty in a new-look outfit.

"I like his (German's) game style and the fact that everyone's on board, he's transparent with it and clear with how he wants us to go about it, I like that a lot," Nastasi said.

"He likes to move the ball and have a crack at the game."

Nastasi is only 170cms but strong at 75kgs and has good pace.
