On Sunday Bosnich will start in goal for the first of a likely five-game A-League stretch with the Central Coast Mariners against the Roar at Suncorp Stadium.

"We saw Mark play against Sydney in the pre-season cup and he was exceptional," said Farina of Bosnich's only previous appearance for the Mariners last month - a 3-0 win over Central Coast which included a Steve Corica penalty save.

"Mark's been there and done that and I don't think nerves will play any part in it."
