Juventus 3 – 1 Napoli
Napoli were left reeling after Juventus were awarded two penalties early in the second half on their way to a 3-1 win in the first leg of their Italian Cup semi-final on Tuesday.
Jose Callejon had given the visitors the lead after a flowing move.
But Argentine Dybala levelled for the Serie A leaders, converting a spot-kick he was clipped by Kalidou Koulibaly.
Gonzalo Higuain put the hosts ahead from a tight angle before Dybala added his second, converting after keeper Pepe Reina hauled down Juan Cuadrado.
Napoli saw their own penalty appeal turned down immediately before Juventus’ Paulo Dybala tucked home his second goal from the spot.
Higuain left Napoli to join Juventus in July, having scored a record 36 Serie A goals for them last season.
The second leg takes place next Tuesday in Naples.
