Sydney United star midfielder Glen Trifiro received some very welcome news this morning, the Central Coast Mariners had signed him until May 31.

"I'm still a bit shocked," Mr Trifiro said.

"I'm just about to meet my brother (Wanderers star Jason Trifiro) for some lunch."

Trifiro had a stellar season with Sydney United 58 FC last year.

The accolades included the John Kosmina Medal for best player in the National Premier League final, where his team was victorious.

He also scored the opening goal in the final where United beat South Hobart 2-0.

It won't be the first time the midfielder has made the journey north to the Central Coast as he spent time with Mariners during his junior career.

Trifiro said he was hopeful he would be able to make a solid contribution to his new club.

But he also highlighted the great program at United which helped him move to bigger and better things.

"They're a top Premier League Cup, you can't say more than that."
