The Brazilian playmaker, who has scored seven goals in 24 appearances this season, could even miss the grand final, should Victory make it, with his contract due to expire on 30 April.
That’s five days before this season’s decider.
Back to his best after his recovery from anterior cruciate ligament injury which saw him used sparingly early in the campaign, Finkler, 28, is attracting interest from his native Brazil, Asia, Europe and several other A-League clubs as he ponders a probable future away from AAMI Park.
Instrumental in Victory’s surge to third spot on the ladder, he has consistently side-stepped talk over his future as his contract nears its end, but unless Victory ups the ante in the coming weeks it looks likely he will follow fellow midfielder Mitch Nichols out of the club he joined in June 2012.
Victory’s top scorer James Troisi, on loan from Atalanta, is also likely to depart at the end of the season.
Finkler’s agent, Sydney-based Lou Nesci, said: 'Gui is focused on the last few games getting to the grand final.
'His future is equally important to him but he is no rush to jump into signing if the deal is not right.
'There is no shortage of interest for a quality player like him so I'm sure the right deal will be secured eventually.
'But if he puts pen to paper with Victory it would be great for them and the A-League.
"For Gui, the positive remaining at a great club like Victory would be stability for him not having to move.
'As already mentioned, for now Gui will sit tight focus on continuing his good form and doing his best for the club."
Should Victory make the grand final, and Finkler remains unsigned for another season, it is possible the club could extend his deal by a week to ensure his inclusion in its starting line-up.
