Central Coast manager Lawrie McKinna believes Mark Bosnich's comeback could take him back to Europe.

Bosnich came off the bench to make two good saves in an impressive 30-minute performance as the Mariners beat the Queensland Roar 2-1 in a Pre-Season Cup clash on Sunday.

With Danny Vukovic set to miss five rounds of the season as a result of his tangle with referee Mark Shield in last year's grand final, McKinna is keen to have Bosnich available to step in for the Mariners.

"Last week he did a bit of all right and then today when he came on he made a couple of point-blank saves," McKinna said.

"He's been fantastic. He's training hard, he's keen, he's a pleasure to work with and today he showed again that he's still got it."

"We're not looking at Mark for the season, we're looking at the five-game gap when Danny is suspended."

Bosnich is making his comeback after several years out of football since his Chelsea contract was ripped up in 2002 following a failed drugs test.

Sunday was his second appearance in a pre-season game for Central Coast.

McKinna believes Bosnich is enjoying the quieter life of Terrigal but suspects that Europe will come calling sooner rather than later.

With Vukovic one of the country's best developing keepers and goalkeeping coaches already in place, the Mariners mentor does not expect to be able to hold on to the former Aston Villa and Manchester United stopper in the long term.

"We're a very small club," McKinna said.

"If he keeps doing okay, there's no reason why he can't (get back to Europe). And maybe that's the platform Mark is looking for.

"When the transfer window opens up over there opportunities are going to arise.

"If he is playing and playing well here, well, the games are televised over there and people are going to see he's keen and has his head switched on."
