The Spaniard wants his side to stay true to their philosophy when they take on Real Madrid in the Champions League final
Diego Simeone's men face city rivals Real Madrid as they look to complete a double, having already won La Liga on the final day of the season thanks to a 1-1 draw at Barcelona last week.
Garcia has vowed that his team-mates will remain true to their philosophy in Lisbon and is certain that they can pip their city rivals to the title.
"It's something every player dreams about," he told reporters.
"We know how much it would mean to win it and we are going to be completely up for it. Now, more than ever, it's vital that we are up for it and have confidence in our way of doing things.
"That's what's got us this far. If we do our job, we can come out on top."
Real Madrid and Atletico kick off at 20:45CET in Lisbon on Saturday.
