It all happens in the first half, when Doveri awards the penalty to the Bianconeri but then changes his decision after the on field review
Key episode in the 13th minute of the first half of Fiorentina-Juve, when after a tackle in the area between Vlahovic and Pablo Marì Doveri whistled a penalty for Juve. After the check in the VAR room, Guida calls the referee back to the monitor, who following the review announces the revocation of the sanction. The images actually show a mutual holding back: it is true that Marì’s is more conspicuous, but it is Vlahovic who starts to take the leading position. It would have been better not to whistle anything.
