Fremantle coach Ross Lyon says the midfield battle will play a key role in deciding the winner of Saturday night’s AFL clash with Sydney at Domain Stadium.

Both sides enter the match with an unbeaten record this season, but Lyon says that will count for little on match day.

“There’s a lot been written, but at the end of the day, each team has only won three games. It’s not like we’re coming in 13-0 each,” Lyon said.
