Sydney FC coach Frank Farina doesn't know if his side's do-or-die finals clash against Melbourne Victory on Friday could be his last game at the helm of the A-League club.

But the embattled mentor says he won't let the constant pressure and scrutiny affect him or his team as they vie for a spot in the semi-finals.

Having beaten Perth last week to secure fifth spot on the ladder, the Sky Blues travel to Melbourne for the Etihad Stadium encounter against fourth-placed Victory.

Farina's contract for next season was said to be dependant on him securing a top-four position.

With that not achieved, now it's believed the only thing that can save his job is a championship.
