GEORGE Hewett has attracted plenty of focus in the lead-up to Saturday's Sydney derby elimination final at the SCG, but he's not the only Swan capable locking down on one of Greater Western Sydney's star midfielders.

Gun Giant Josh Kelly is the player most likely to find himself with the Hewett tag, but the speedy Harry Cunningham could be an option to help with the assignment.

Kelly won the GWS club champion award and was named All Australian in 2017 after starring mostly as an inside midfielder, but he does mix his time onball with periods on the wing, which is where Cunningham comes into play.

The 24-year-old is fresh off playing a key role in shutting down Hawthorn wingman Isaac Smith and has the running capability to do a similar job on Kelly, allowing Hewett to switch his attention to Stephen Coniglio, Callan Ward or Dylan Shiel.

Cunningham, who has played all 22 games this year and averaged a career-high 18.1 possessions per match, told AFL.com.au being given a task on an opposition star gives him an advantage on game day.

"It gives you a starting point I guess, then from there footy is footy and you're just got to go and play the game," he said.

"I enjoy those roles and you learn a lot from playing on those guys, especially someone like Isaac who has played in a lot of finals and enjoyed premiership success.

"Isaac such a good runner with his endurance and speed, so I just tried to negate his influence on the game without trying to go away from how I like to impact the game for our team.

"It's a great challenge, and if those roles are given to me I try and take them with both hands."

Cunningham's run makes him an important player to the Swans, especially given the home side doesn't have the pace to match the Giants through the midfield, but he said Sydney's clearance and contested ball-winners Josh Kennedy, Luke Parker, Hewett and Isaac Heeney were the key to beating the visitors.

"First things first we've got to win the footy, and if you take the footy away from them you can stop that explosion from the stoppage that they possess," he said.

"The Giants run hard both ways and they've got a lot of leg speed all across the ground, to be honest with you.

"They're very good at winning the footy and exploding from the contest, so if we can work hard at the coalface, get it forward and lock it in our half, it will go a long way towards limiting the influence that their midfielders can have on the game."
