Port Adelaide have reportedly approached Sydney defender Aliir Aliir as they look to take the next step towards a premiership.

The Power's current crop of key defenders were found out at times in 2020, with the club now turning their attention to the the trade window, with Aliir in their sights.

With Port Adelaide trading Dougal Howard 12 months ago and current defensive duo Trent McKenzie and Tom Clurey struggling at times to match some of the league's best forwards, Ken Hinkley looks to be pushing for reinforcements.

According to SEN SA's Miles Pfitzner, the Power have approached Aliir.

“Apparently the Sydney Swans player Aliir Aliir has been offered a contract by Port Adelaide,” Pfitzner told SEN SA Drive.

“He’s still contracted at the Swans, but Port is very interested and has offered him a contract to join the Power in 2021.”

Port Adelaide assistant Michael Voss said the Sydney tall would be a great fit for the Power's defence.

“(Aliir) probably would (bolster our backline). I can’t speculate about our level of interest in him, but I know there’s a lot being talked about our back six and what it should look like. I think our guys have stood tall all year,” Voss said.

“You’d look at bolstering any area, but the guys and the jobs they’ve done down there have been superb, but we’re always looking to get better.”

Aliir, an East Fremantle product, has played 64 games for the Swans since being drafted to the club in 2013.
