Barella, the home side's best player, was already on a yellow card when he caught substitute Miralem Pjanic late from a Juventus throw-in. Allegri's side recorded a fifth successive Serie A win, restoring their seven-point lead after it had been cut by wins for Napoli on Friday and Roma earlier on Sunday. Roma's 2-0 win at Crotone moved then above Napoli into second - and came with a goal and a penalty miss from Edin Dzeko, who is level with Higuain on 18 league goals.
