Cristiano Ronaldo scored a penalty with two minutes remaining as the defending champions somehow avoided their first Serie A defeat in the season with a come-from-behind 2-1 win away to Lazio.
Substitute Joao Cancelo's first Juventus goal looked to have salvaged a fortunate point for Juve, but they then went one better as he then won a late penalty which was converted by Ronaldo, his 15th league goal of the season.
Cancelo, having just come off the bench, had struck with 16 minutes remaining, cancelling out Emre Can's earlier own goal as Juve moved to 21 games unbeaten in the top flight this season.
