Rome: Fiorentina risked an own goal just five minutes into the game, before keeper Pietro Terracciano performed a double save to deny Inter.
Inter Milan were utterly dominant at the San Siro but were unable to break down a stubborn Fiorentina defense, and the resulting 0-0 draw meant Juventus moved a step closer to their ninth consecutive Scudetto in the ongoing Serie A.
With Romelu Lukaku back from injury, Inter coach Antonio Conte on Wednesday preferred Alexis Sanchez over Lautaro Martinez to partner the Belgian, while Christian Eriksen returned to the starting line-up, reports Xinhua news agency.
The Nerazzuri used their aggression and tempo to press high from the beginning.
Fiorentina risked an own goal just five minutes into the game, before keeper Pietro Terracciano performed a double save to deny Inter.
