Andrea Cambiaso struck with virtually the last kick of the game as Juventus climbed to the top of Serie A with a 1-0 win over Hellas Verona.
Moise Kean had earlier seen two goals disallowed by VAR as Verona chased an unlikely point in their battle against relegation.
Verona have never won away at Juventus in Serie A history and that record now stands at 33 matches, following a heartbreaking defeat.
Juve thought they had taken the lead in the 13th minute when Kean, after 10 league games without a goal, spun his marker 25 yards out and launched an unstoppable drive past Lorenzo Montipo.
But the VAR took the play back to when Kean originally collected the ball before turning back on himself and adjudged him fractionally offside.
Kean was denied again moments later when his header from Manuel Locatelli’s corner was tipped over by Montipo.
The Italy striker, still aggrieved at having his goal ruled out, beat another couple of challenges on the edge of the box but, having been forced wide, he lashed his shot off target.
Verona weathered the storm and fashioned a couple of half chances, but Michael Folorunsho and Milan Djuric fired wide while Wojciech Szczesny saved from Federico Bonazzoli just before the break.
Kean squandered another presentable chance early in the second half when he planted a free header wide.
His frustration grew to boiling point when he glanced a superb header home after a sweeping Juve attack, only for VAR to haul it back for a foul by the forward in the build-up.
The 23-year-old was promptly booked for hurling the ball away after another decision went against him.
An 11th match without a goal came to an end on the hour when Kean was replaced by Federico Chiesa.
The substitute was immediately in the thick of the action, forcing Montipo to acrobatically tip his shot over the top.
Chiesa had his head in his hands moments later when he received a cut-back from the byline, only to see his first-time shot from 10 yards cleared off the line by Davide Faraoni.
Federico Gatti tried his luck from 25 yards, but his fierce drive flew wide and teenage substitute Kenan Yildiz lifted a glorious chance too.
But Juve’s moment came at the end of six minutes of stoppage time when Arkadiusz Milik’s header came back off the inside of the far post and Cambiaso smashed in the rebound.
