After two frustrating seasons in Perth, Rizzo will play with the Mariners throughout the Champions League and he needs to discover his best form to convince Central Coast officials he is worth a permanent deal with the Mariners.

But if determination and hard work at training is any indication, Rizzo is well on the way to securing a long-term contract with the Mariners.

Rizzo played strongly in midfield as the Mariners lost 1-0 to fellow Champions League contenders Newcastle last Tuesday and reflecting on his first few weeks at the club, he said: "So far so good.

"I didn't play as much as I would have liked at Perth so when his opportunity at the Mariners came up I jumped at it.

"The Mariners have been one of the most successful clubs in the A-League and I'd love to be part of that after the Champions League.

"It'll be a real challenge for the team and for me but I'm up for it."

Rizzo, a former Liverpool player, said he feels like he still has something to prove despite enjoying success overseas, especially with Crystal Palace in England.

He believes the Mariners will hit back hard in the Champions League after a poor end to the A-League.

"There's plenty of talent in the squad," he added. "I'm sure the club will hit back. Everyone is buzzing about the Champions League, it's a great opportunity to play at a higher level. It's a fresh start for me and the club."
