Mario Mandzukic's volley has given Juventus a 1-0 lead over Manchester City after 45 minutes of their Champions League encounter in Turin this evening.
Fernandinho went close with a fierce low drive in the fifth minute after Juventus could only clear a corner straight to the Brazilian midfielder.
Mandzukic and Paulo Dybala then sent efforts wide of the target, but the Juventus strikers were offside on both occasions.
Man City's best chance of the half fell to Fernandinho, who reacted quickly after Giorgio Chiellini's challenge on Yaya Toure broke inside the area in the 16th minute, but the midfielder blazed the ball high over the bar from 15 yards.
Two minutes later, the hosts took the lead as Mandzukic shrugged off a weak challenge from Nicolas Otamendi to volley home Alex Santos's left-wing cross.
The Croatian striker almost doubled his tally in the 28th minute with a swivelling half-volley, but Joe Hart dived low to his left to keep out his effort.
Toure then saw his 30-yard strike curl inches wide of the far post with Gianluigi Buffon stranded, and the Ivorian had another opportunity a few moments later, but he scuffed a weak effort wide.
Hart made a crucial save shortly before half time as he flung himself at the feet of Stephan Lichtsteiner, who raided forward from right wing-back.
Buffon kept his side ahead in the 44th minute as he rushed from his goal to deny Sergio Aguero, who couldn't take advantage of a one-on-one chance after being presented the ball by Claudio Marchisio's blind back-pass.
