Nick Dal Santo believes his former team, North Melbourne, are set to continue improving in 2019.
The Kangaroos surprised many in 2018 with a season that saw them miss the eight by one game.
Impressive wins over GWS, Hawthorn and eventual premiers West Coast highlighted a year that saw a number of their players flourish into A-grade performers.
“I think what they showed last year impressed a lot of people,” Dal Santo told SEN Breakfast.
“I put my hand up, I did not expect the turnaround in form and results to be that quick.
“I think Jack Ziebell could kick 40 goals – two per game if he plays as a permanent forward,” he said.
“I think they can shake it up a bit next year. Brad Scott is really good at finding the elite qualities in players.”
