Juventus punched their ticket to the Champions League's last 16 as Mario Mandzukic scored in a narrow win over Valencia in Turin.

Mario Mandzukic's 59th-minute winner earned Juventus a 1-0 victory over Valencia that ensured they booked their place in the knockout rounds.

The Bianconeri were stunned by Manchester United in Turin during their last group game but sealed their place in the last 16 with one game to spare on Tuesday, with Group H top spot now up for grabs on matchday six.

In a game of few chances, Mandzukic scored a tap-in in the second half after Cristiano Ronaldo had worked space to steer a cross to the Croatian striker.

Juventus continued to look short of ideas until Ronaldo's moment of magic just before the hour mark.

The Portugal forward's stepover fooled Gabriel and gave him enough space to steer across a ball that Mandzukic turned home from close range.

Valencia thought they had hit straight back when Diakhaby got a touch to Dani Parejo's near-post free-kick.

Neto denied Paulo Dybala, Ronaldo and Mandzukic a second Juve goal, but Valencia never looked like getting an equaliser at the other end as they exited the competition.
