Juventus manager Massimiliano Allegri has called on his players to regroup and focus on the next game after being beaten by title-chasing Napoli in Serie A on Sunday.

Kalidou Koulibaly scored a 90th-minute winner in Turin to move Maurizio Sarri's charges to within just a single point of the league leaders with four games remaining.

"We have to get over this one quickly," Allegri told the club's official website. "Anything can happen in a one-off head-to-head. We struggled a little towards the end but we needed to see the game out.

"It was a match we didn't want to lose but let's not forget that we're still a point ahead and we just need to hold onto our lead. We have two home games and two away games left, starting at San Siro, and next week will be a decisive game for us."

Juve's remaining league fixtures see the Old Lady take on Inter Milan, Bologna, Roma and Hellas Verona.
