Star Collingwood ruckman Brodie Grundy has held off contract talks with the club until next year, according to a report by The Herald Sun.

The in-form big man will be one of the most sought after free agents when his current deal expires at the end of 2020 and is likely to command a six or seven-year contract worth over $1 million a season.

Collingwood list manager Ned Guy has begun talks with Grundy's manager, Robbie D'Orazio, but neither party are said to be in a rush.

But with a bursting salary cap, the Pies will have to figure out a way to accommodate for Grundy's impending seven-figure pay day, while star duo Jordan de Goey and Darcy Moore also come out of contract at the end of 2020.

The South Australian recently admitted he would consider moving back to Adelaide, but the Crows or Power are yet to declare interest in him.

The breakout form of emerging Crow Reilly O'Brien, who has taken over the mantle of the club's No. 1 one ruckman from Sam Jacobs, may have lessened the Crows' interest in Grundy.

Coming off a massive performance in Collingwood's win over the Bulldogs last week, the All-Australian became the first player in AFL history to tally 50 hit outs, 25 disposals and two goals in a game.

Grundy has averaged 20.9 disposals and 5.8 score involvements per game this season, the most of any ruckman, as well as 42.5 hitouts.
