Look at Manny. Did he play holding CM for Green Gully? Don't think so. Same for Lia.
This from Manny's Phoenix website: "A versatile defender who has excelled in the Victorian Premier League, Muscat adds even more pace and skill on the Phoenix�s flanks. Has the ability to play on both sides at the back and has played regularly as a defensive midfielder with Green Gully."
And I am sure that CM has always been Lia's preferred position.
