Juventus striker Carlos Tevez smashed home a second-half penalty as the hosts stunned Real Madrid with a 2-1 win in an absorbing Champions League semi-final, first leg.
The irrepressible Argentine, playing some of the best football of his career, won the spot kick just before the hour when he was upended by Dani Carvajal following a breakaway and tucked it away in a pulsating, wide open game.
Juve's Alvaro Morata had opened the scored against his old club in the ninth minute in front of a boisterous home crowd but Cristiano Ronaldo headed the equaliser for Real in the 27th.
The game could have turned out very differently for Real but forward James Rodriguez wasted a glorious chance when he headed against the bar from point-blank range before the break.
