The Stadio Olimpico side have made a stunning start to the campaign but their coach insists challenging Juventus is going to be beyond his team
The unbeaten capital club have made a flying start to the 2013-14 season, sitting top of the league with 10 wins and two draws from their opening 12 games.
Roma have only conceded three goals in the process and are being tipped to challenge champions Juventus - who they lead by one point - to the title but Garcia believes that will be a step too far this year.
The coach told Gazzetta dello Sport: "Juventus have been built to win the Scudetto – we are not at that level just yet.
"If we finish in the top five that would be a very good result for us."
But after finishing last season in sixth-place, Garcia admits the strong start to the season has made even him think about a top-three finish and Champions League qualification.
He said: "Our aim this season has to be qualifying for European competition, perhaps the Champions League.
"It is normal that our fans are dreaming big but I believe we need to try and be realistic.”
Roma take on Cagliari and Atalanta in their next two Serie A games before facing crunch matches against Fiorentina and AC Milan.
