After watching from the sidelines during Sydney FC's opening two trial matches, Aloisi will pull on his boots at Lambert Park in Leichhardt. 

Two overseas triallists will also be given a chance to impress the new coach as he looks to fit the final pieces into his squad.

"Aloisi will play part of the game, short part of the game first time. So far (during the trials) we have been able to pick up good information.  I think it's very important for our season," said Lavicka.

While Sydney's marquee man has been given the green light to play, Steve Corica won't start at Lambert Park, with the captain set to return from minor off-season knee surgery next week against the Northern Tigers.

"He is practising with the team and will play later. They (Corica and Aloisi) are both very important players for our squad, for our way to be successful this year," said Lavicka.

Sydney have at least one spot left to fill in their roster and will continue trialling players during their pre season campaign, with Englishman James Vaughan and Uruguayan Gustavo Latronico set to get their chance to impress tomorrow night in Leichhardt.

The Australian-based international players will take their places in a strong Sky Blues' line-up, with Sydney FC out to make it three straight wins in three community campaign.

The Lambert Park trial kicks off at 7:15pm tomorrow night, with tickets available from the host club.

Meanwhile, Sydney FC's upcoming friendly against Penrith Nepean in two weeks time is shaping up as a showpiece for football in the city's West.

Organisers have today confirmed the clash has been moved to Penrith's CUA stadium, and a big crowd is expected for the game kicking off at 7:30pm on Tuesday, June 9.
