The Catalan coach intends to focus on his team's challenge for A-League silverware before turning his full attention to discussions over a new deal
The Spaniard, 37, is in talks with the club's hierarchy to extend his deal beyond the end of the 2014-15 campaign.
Gombau denied earlier this month he held discussions with Melbourne Heart's new owners Manchester City.
The Catalan was under fire early in the season after his side collected just six of the possible first 27 points.
But he is expected to sign an extension after leading Adelaide to the finals – and possibly second place if final-round results go his side's way.
"We are now under discussions," Gombau told Goal Australia.
"They offer to me an extension and also at this moment I want to be concentrating on these important games and it's something that in the next weeks or when we finish the competition we will arrange."
Adelaide football director Michael Petrillo said the club were in discussion with Gombau and talks were 'proceeding well', without confirming or denying an extension was on the table.
Whether Socceroo Michael Zullo remains at the club along with Gombau is still an unknown.
The 25-year-old is on loan from Utrecht until the end of the season, and Gombau said he would love to have Zullo back for another campaign.
Zullo's contract with the Eredivisie club expires in June 2015.
"I hope, I wish Michael can be with us next season because he's a very good player but you never know in this case," Gombau said.
"We don't have the power to say that he's going to stay with us."
Gombau, who has slowly put in place his possession-based style at Adelaide, said his focus had turned to results late in the season.
If Adelaide win at Newcastle on Friday night and other results go their way, the Reds will finish second and book their place directly in the semi-finals.
"I am happy with what we are doing," Gombau said.
"Now for this moment to be competitive, to try and take this result more than to building the style … now it's the moment to try and win the games and try to win the games and advance in the finals."
