Ciro Immobile scored twice as Lazio cast some early doubt on Juventus' ability to sustain their domination of Italian football by claiming a 3-2 victory in the Supercoppa Italiana in Rome.

Juve - under Antonio Conte and then Massimiliano Allegri - have won Serie A six years in a row, reaching the Champions League final twice in that period and winning the Coppa Italia three times.

But the shock sale of long-serving defender Leonardo Bonucci, coupled with uninspiring recruitment in the transfer window, has created suspicion that the Old Lady's star might be about to fade.

at Juve have work to do before the new league season starts next weekend, with Immobile scoring a penalty before cutting through a soft back-line to double his tally.

Paulo Dybala launched a one-man comeback at the death, steering home a free-kick with five minutes remaining before converting a spot-kick, but Alessandro Murgia rescued the cup for Lazio.
