Khedira gives Juventus second straight win of the season

Both teams struggled to get going on a hot evening at the Stadio Olimpico and the match was halted for a water break in the 28th minute.

Khedira struck in the 66th minute when Paulo Dybala chipped the ball into the area and the Germany midfielder held off his marker and cleverly scored with a shot on the turn into the far corner.

Lazio, who lost four times to Juventus in all competitions last season and have not beaten their opponents since 2003, nearly took the lead minutes earlier when Marco Parolo failed to make contact with Ciro Immobile's ball across the face of the goal.

Juventus, champions for the last five season, have won 28 out of their last 30 games in Serie A and coach Massimiliano Allegri even allowed himself the luxury of starting with new signings Gonzalo Higuain and Miralem Pjanic on the bench.

Argentine Higuain, who scored a record 36 goals for Napoli last season, came on just before Juve's goal.
