Raising his tally to six goals in seven matches since arriving on loan from Chelsea, Mohamed Salah scored twice as Fiorentina defeated Juventus 2-1 in Turin in the first leg of their Coppa Italia semifinal.
Juventus' 47-game home unbeaten streak came to an end. No visitors had won at the Juventus Stadium since Bayern Munich in April 2013.
Salah opened the scoring on a remakable 60-yard run that started in his own half, cut across the pitch past three defenders, and ended with a shot past Juventus keeper Marco Storari.
Juventus' reply may not have been as spectacular but it required no less skill as Simone Pepe and Fernando Llorente combined to level things up 13 minutes later. Pepe provided a perfect cross from the right and Llorente rose to attack a brilliant header which went in off the far post.
Both sides were trying to get forward but Fiorentina were having the more clear-cut chances as Jose Maria Basanta headed against the post and Micah Richards brought a smart save from Marco Storari just after the break.
So it was no surprise when they took the lead, Claudio Marchisio losing possession in midfield and allowing Salah to bear down on goal and coolly slot home.
Juve then had the best of the second half as they pushed for an equaliser but they will have a deficit to turn over in their second leg in Florence on April 7.
Since joining Fiorentina last month, Salah has three goals in Serie A, one in the Europa League, and two in the cup.
Fiorentina stretched their unbeaten run in all competitions to 15 matches.
Lazio and Napoli drew 1-1 in the other semifinal on Wednesday.
