The keys for Swans and Giants

KEY FACTORS FOR SYDNEY AND GWS IN THEIR AFL QUALIFYING FINAL AT ANZ STADIUM:

FOR SYDNEY:

* Slow down the Giants and stop them spreading the ball and allowing the likes of Dylan Shiel, Lachie Whitfield and Tom Scully to cut loose

* Prevent speedy half-backs Nathan Wilson and Zac Williams breaking the lines

* Apply plenty of pressure on Giants backline director Heath Shaw, who initiates so many of their forward thrusts

* Reduce the impact of former Swans ruckman Shane Mumford

FOR GREATER WESTERN SYDNEY:

* Win the inside midfield battle against Josh Kennedy, Dan Hannebery, Tom Mitchell and Luke Parker

* Help Phil Davis by keeping the ball out of Lance Franklin's hands and away from his long-distance boot

* Precise delivery to their potent forwards and away from the competition's stingiest defence

* Try to limit the influence of Swans co-captain Jarrad McVeigh, who rarely wastes a possession
