The Sydney Swans are back in training for the 2017 AFL season.

After a season that saw the Swans go all the way to the grand final only to falter in the face of the Bulldogs unstoppable charge to its inaugural  AFL premiership, the Sydney team have plenty to prove.

Swans midfielder and Rising Star winner Callum Mills (pictured) says at this stage, the premiership race is wide open with a number of clubs capable of going on to the flag in 2017.
