Watch: Juventus extends record win streak after dubious late penalty

Juventus forward Paulo Dybala converted the second-latest goal in Serie A this season - which also stood as Friday's match-winner - after the referee awarded a controversial penalty deep into second-half stoppage time against AC Milan.

Match official Davide Massa pointed to the spot in the 95th minute after Stephan Lichtsteiner's cross made contact with the arm of Mattia De Sciglio.

A massive crowd formed around both the referee and the official behind the goal as Milan protested the decision.

It seemed like a harsh call - De Sciglio's arms were in a running position, and Lichtsteiner's delivery came from barely a foot away, leaving almost no time to react.

The International Football Association Board's rules stipulate that "the position of the hand does not necessarily mean that there is an infringement," which could apply in this case.

Regardless, Massa believed he saw enough, and Dybala subsequently blasted the last kick of the game to hand the home side a 2-1 victory, extending Juve's home winning streak to a Serie A-record 31 matches.
