Lazio have the edge over Juventus after coming from behind to triumph 2-1 in the first leg of their Coppa Italia semi-final.
Goran Pandev and Tommaso Rocchi scored second-half goals as Lazio came from behind at the Stadio Olimpico.
Juve, who had a Vincenzo Iaquinta goal wrongly disallowed for offside, took the lead through Marco Marchionni's deflected shot after 34 minutes yet were soon on the retreat as goalkeeper Alex Manninger repelled Rocchi and Cristian Ledesma.
The Austrian could do nothing to keep out Pandev's low drive on the hour mark, however, and was beaten again with 12 minutes to play as Rocchi outstripped Giorgo Chiellini to convert Francelino Matuzalem's through ball.
The tie concludes in Turin next month, while Wednesday's second semi-final sees Sampdoria host league leaders Inter in the first leg of their showdown.
