The leaders and reigning champions sent out a statement at the Juventus Stadium on Sunday with a comfortable victory, while the Giallorossi finished with nine men after an ill-disciplined end to the match.
The capital side are now eight points behind the Bianconeri but Garcia insists all is still up for grabs, although Scudetto success is not top of the agenda at the Stadio Olimpico.
"There are another 60 points available," the former Lille boss told Sky Sport Italia. "But the title is not our objective.
"Our objective is to get back into Europe, so we are now second and that is a good place to be in. After that, we'll see what happens."
A combination of poor defending and a ruthless streak in front of goal exhibited by Antonio Conte's side left Garcia ruing a feeble surrendering of Roma's undefeated start to the Serie A campaign and the lack of discipline shown towards the final whistle clearly rankled with the 49-year-old.
"I don't know if this was the worst way to lose our unbeaten record, but it is bad to end with nine men," the French coach continued.
"At 2-0 we still had the chance to get back into the game, but we were unlucky to concede the two goals in bad moments of the match.
"Unfortunately, they scored at the first chance and we didn't take ours. It hurt to concede straight after the restart. Juve did well on set-plays and we have to work on some issues.
"In my view it is a problem of efficiency. Neither side had that many chances, so you've got to take them when they arrive. We know this is football and Juve have a ruthless team, so we must learn to be ruthless too.
"It is always difficult to play away to Juve and keep a clean sheet. They have very strong strikers, but I have no doubt that in the first half we played the right game. In order to win you also need luck in important moments and the luck was more with Juventus than with us."
