Shinji Okazaki and Riyad Mahrez had the Premier League champions two goals ahead before Jose Izquierdo pulled one back for the rock-bottom Belgians, but it was all too late as Claudio Ranieri's men confirmed top spot with a fourth win in five outings.
In Denmark, FC Copenhagen and FC Porto played out a 0-0 draw which still has second place up for grabs when they take on Brugge and Leicester respectively on Matchday 6 early next month.
Goals from Djibril Sidibe and Thomas Lemar bookended Harry Kane's penalty as Spurs crashed out at the group stages with just four points from five games as they now look to wards the Europa League by avoiding defeat to CSKA Moscow at Wembley in a fortnight.
Nicolas Pareja and Claudio Marchisio had traded goals before Leonardo Bonucci and Mario Mandzukic contributed late for the Juve cause, enabling the Bianconeri to sit a point ahead of Sevilla who must avoid defeat to Olympique Lyon in the final game to progress.
