Handed a two-year contract extension this week, Gombau will have the chance to continue putting his vision into action.
"Tomorrow I want to start to work," the 37-year-old said.
"I am excited to work and to do the job the best that we can and to start to sign new players and to bring this philosophy and try next season to be in the top.
"I think we can improve a lot."
As has been the case several times this season, the Reds dominated possession on Saturday night but failed to turn that advantage into goals.
Gombau admits the Reds finishing the season two places lower than last year is by no means a success, but remains adamant he's put in place the foundations for his exciting brand of football to deliver results in the future.
"Finishing sixth cannot be successful," he said.
"If you ask me about the steps we have taken from the beginning, I am satisfied in the way we are playing.
"Today everybody knows what they need to do, we play good football, the players know the movement and this is difficult.
"But successful? No. Successful is to be in the final, is to play in Asian [Champions League]."
