Juventus moved eight points clear at the top of Serie A thanks to a hard-fought 1-0 win at home to Roma on Saturday night.
The only goal came ten minutes before half-time when Mattia de Sciglio's lofted cross was headed home at the far post by Mario Mandzukic.
Roma were defensively disciplined up to that point, and had their goalkeeper Robin Olsen to thank for keeping the scores level with the Swede producing a hat-trick of great saves throughout the first half.
However, Mandzukic's towering header broke the deadlock shortly before the interval, for his eighth Serie A goal of the season.
