Milan (AFP) - Misfiring Paul Pogba could start on the bench while new defender Alex Sandro could make his debut as Juventus travel to Roma in the first big clash of the fledgling Serie A season on Sunday.Pogba's first league outing of the campaign ended in disaster, for both the star midfielder and the Italian champions as he adjusts to life without former teammates Arturo Vidal and Andrea Pirlo.Juventus dominated throughout, failed to hit the target on nearly a dozen occasions and Pogba, who looked lost amid a new-look midfield, capped a poor performance with a ridiculously wide free-kick attempt that became a Twitter sensation for his detractors. In the end the champions fell to a 1-0 home defeat against Udinese, so they can ill afford another reverse in a match that, this time last year, produced a bad-tempered affair which well and truly ignited the rivalry between the two sides for the rest of the season.Adding fuel to the fire is the fact referee Nicola Rizzoli will take charge of Sunday's afternoon fixture.Having sent a player off from each side and sent Roma coach Rudi Garcia to the stands, he became a hate figure for Roma's supporters and, as the affair escalated, was later sidelined by Serie A officials after admitting he could have handled the match better.Pogba's poor start could see him start on the bench in place of Simone Padoin while coach Massimiliano Allegri could give recent signing Sandro his debut.Sandro has largely been used at left-back but his marauding runs and skill on the ball mean he would also fit nicely on the wide left position in midfield if Juve, as expected, deploy a 3-5-2 formation.Sandro, unveiled in midweek, said he is raring to go."We meet Roma next week and, like all 'clasicos', it will be a tough game.
