Injured Saints forward Josh Bruce says emerging teammate Jade Gresham has untapped star power potential.

Gresham is enjoying a breakout season for St Kilda, booting 28 goals for the season including the match-winner against the Suns during round 13.

And Bruce thinks he has seen enough to suggest that the 20-year will be one of the top tier players of the competition one day.

โ€œI donโ€™t want to put too much pressure on the kid because heโ€™s young, but heโ€™s starting his career off like a Robbie Gray or even a Gary Ablett,โ€ Bruce told theย AFL Nation pregame showย before Friday night's game.

โ€œHe's just an elite, elite small forward. He hasnโ€™t got the tank yet, but you never know (if he could go into the midfield).

โ€œIn three or four years, you never know what he could become."
