Chris Dittmar has dropped a massive footy rumour this morning regarding one of Port Adelaide's most important midfielders.

Speaking on his Triple M Adelaide breakfast show, Roo and Ditts, this morning, Ditts reported that two Melbourne-based club's have offered outside midfielder Jared Polec a substantial contract should he decide to leave the Power.

"There are two club's in Melbourne circling," Ditts said.

"And when I say circling, they've offered substantial money.

"There very interested in him because of his outside run.

"North Melbourne still have a bit of money at the moment...I'm led to believe that North Melbourne will throw big money at Jared Polec.

"And the other club that is more than likely to get him (should he leave Port), is St Kilda."

Polec is having the best season of his career in 2018, averaging 24.7 disposals and 3.5 tackles a game.
