The 1-0 extra-time victory over Flamengo in Doha saw the Reds win the one trophy available to them which they had not previously won.
With a third trophy in six months in the bag, Gomez says they are now looking to consolidate their bid for a first league title since 1990.
"Winning this only adds to our positivity," he said. "We come away from here as champions of the world. Why can't we use that as a positive?
"But we know we can't dwell on anything. We're not even halfway through the season yet, so it's a case of heads down and carry on the focus."
