Former Port Adelaide midfielder Kane Cornes believes Power star Robbie Gray is one of the best players in the club's history.

Gray was instrumental in the Power's five-point win over Adelaide in Showdown 44, booting six goals for the match, including five in a dominant third quarter performance.

The 30-year-old has been a star for the Power over the past few years, and Cornes rates Gray among some of the best players to ever pull on the Port Adelaide jersey.

“I’ve got him in third right now,” Cornes told SEN Breakfast on Monday.

“I’ve got Warren Tredrea at number one and Gavin Wanganeen at number two, albeit a lot of Gavin’s great work was done at Essendon.

“Gray’s coming: three best and fairests in a row and he’s probably tracking to win another one this year.”

Gray is currently on track for a record year disposals-wise, averaging 27.1 through seven games this season.

He's also averaging 4.4 marks, 5.0 tackles, 5.9 clearances and 1.4 goals per game, helping the Power to a 5-3 start to the season.
