The 39-year-old manager reserved special praise for Marko Bakic, Joaquin and Borja Valero after a 3-0 win over the Romanian side left them on the brink of the Europa League last 32
The former Spain winger scored a sensational solo goal to get the ball rolling at the Artemio Franchi, with Ryder Matos doubling the lead soon after.
Juan Cuadrado made the victory safe after half-time and Montella was in no doubt as to who was responsible for their third win from as many games in the competition.
“Bakic had a rough start, as he was a bit tense, but he played very well in front of the defence," he told Sky Sport Italia. "By the end of the match he was running the midfield.
“Joaquin put in a great performance. He has exceptional quality, but is finally finding the right level of consistency.
“As for Borja Valero, like many Spaniards he trains during the game and jogs in training. He never stops on the pitch."
Fiorentina, who have conceded just one goal so far in Europe, need just one more win to be sure of a place in the last 32.
