Juventus moved back to within a point of Serie A leaders Napoli as a solitary goal from Douglas Costa proved enough to clinch a nervy 1-0 win over lowly Genoa.
After Napoli overcame Atalanta by the same scoreline on Sunday, Massimiliano Allegri’s side kept pace with their table-topping rivals thanks to Costa’s 16th-minute strike.
The Brazilian’s burst in behind Genoa’s defence allowed him to poke home Mario Mandzukic’s perfectly weighted pass from close range and give the Bianconeri a deserved lead.
However, returning to domestic duties following the mid-season break, the hosts struggled to create too many clear-cut chances in a game that saw them once again without the services of injured top-scorer Paulo Dybala.
They had to instead rely on a rock-solid defence to retain their advantage through to the final whistle, as a sixth straight clean sheet at the Allianz Stadium secured three precious points in a two-horse race for the title.
