Following the Stadio Olimpico side's victory over the Bianconeri in midweek, the French coach is hoping that other sides can find chinks in the Serie A leaders' armour
The Giallorossi avenged their 3-0 defeat in Serie A at the start of January by knocking the Bianconeri out of the Coppa Italia on Tuesday, securing a spot in the semi-finals in the process.
The Stadio Olimpico trainer is thrilled at the way his team rattled the Scudetto holders and, though they sit eight points adrift of Juve in second place still, he says his players will be ready to pounce should Antonio Conte's men slip up.
"Juventus are not unbeatable," Garcia proclaimed to reporters on Saturday ahead of Sunday's visit to sixth-placed Hellas Verona.
"Destiny is not in our hands though, so now we just think about tomorrow's race, to win it, and move forwards from there.
"We must be ready to take advantage of any drop of form from Juventus.
"It was important to win against Juventus, we had the opportunity to play at home where the fans are important and now we are sure to be feeling confident.
"Juve never or rarely lose - we believe that the victory was deserved and it gives a much-needed boost to my squad."
Roma led the Serie A rankings for a long spell earlier in the season following a 10-game win streak, but four subsequent draws allowed Juve to regain the advantage.
