Exciting Sydney AFL youngster Isaac Heeney will urge Swans coach John Longmire to give him more time in the midfield after committing to a five-year contract extension.

Heeney, 20, who is now tied to Sydney until the end of 2022, played most of his first two seasons up forward, but was given time in his favourite midfield area towards the end of 2016.

“I’m out there running my butt off just to push and get that fitness under my belt to be able to run out a game in the midfield, so I’ll be in Horse’s (Swans coach John Longmire’s) ear constantly just saying ‘get me in there’,'” Heeney said.
