Free-scoring Juve thrash ten-man Roma
Arturo Vidal scored twice in the first eight minutes as I Bianconeri responded well to Milan's surprise home draw with Bologna earlier in the day.
Claudio Marchisio completed the scoring in the 52nd minute to round off a comprehensive win which, regardless of the red card, was never in any doubt.
Juve were quick out of the blocks, with Vidal putting them in front in the fourth minute. Paolo De Ceglie's square ball was behind Mirko Vucinic but perfectly placed for Vidal to curl his shot into the far corner beyond the reach of Stekelenburg.
Stekelenburg got his fingertips to Vidal's next effort in the eighth minute, but he was still unable to keep the ball out. Vucinic progressed with the ball at his feet and played it to his right, where Vidal rifled in a venomous shot into the far corner.
Stekelenburg sent off
The game was practically over as a contest when the referee awarded a penalty and sent Stekelenburg off when Marchisio appeared to leap over his outstretched arms. Gianluca Curci came on and actually saved Pirlo's penalty, but the Juve captain was quickest to react to convert the rebound.
Marchisio completed the scoring in the 52nd minute, thanks again to former Roma striker Vucinic. The Montenegrin's perfect control took the pace out of a cross from the left and teed the ball up for Marchisio, who swept a shot past Curci from the edge of the area.
Marchisio brought an excellent save out of Curci in the 71st minute before Juve took the pace out of the game and began conserving energy for their trip to Cesena on Wednesday.
