Sami Khedira hit a second-half winner as champions Juventus made it two wins from two at the start of the new Serie A season with a 1-0 victory away to Lazio on Saturday.

Juventus, who started their title defence with a 2-1 win over Fiorentina last week, were kept on a tight rein by Simone Inzaghi's hosts throughout a first half of few chances at the Stadio Olimpico.

But less than a minute after record summer signing Gonzalo Higuain came off the bench to replace Mario Mandzukic midway through the second period, Germany midfielder Khedira was set up by Paulo Dybala and beat Federico Marchetti at the 'keeper's far post.
