Mancuso, who returned to the Ovens Valley this year from Melbourne, is on top of the star player award half way through the season and among the leading goal scorers.

But Diamonds captain Bonnie Denison said they have the key to nullify her.

“We know how Mancuso plays, her strengths and weaknesses,” she said.

“Bree Buckingham plays really well on her and she is likely to tag her, try to get Christina out of the game.

“It’s not too hard to frustrate Mancuso so we’ll just annoy her and try and put her off her game.”

The ladder leaders are also expected to welcome back Jacqui Hawkins from injury this weekend.

Denison said Diamonds would not go away from their structure but had been working on putting the ball in the back of the net.

“Being on top of the ladder there is added pressure with teams setting up more defensively,” she said.

“We won’t change the way we play but we need to be more attacking and we need to build the confidence of our strikers to shoot.”
