Vlahovic struck his sensational blows in the first half, the first a curling, dipping shot from distancein the 15th minute before then striking a wonderful free-kick in the 37th as Massimiliano Allegri's side extended its unbeaten league run to 15 games.

Substitute Federico Chiesa sealed the win in the 89th minute to ensure Juve remains in second place on 49 points, two points behind leader Inter Milan and seven above third-placed AC Milan.

Sassuolo, meanwhile, sits in 14th, with only two points separating it from the relegation zone.

Domenico Berardi had a chance to cut the arrears in the second half but failed to beat Wojciech Szczesny, as the visitors otherwise put up little resistance after falling two behind.

It was an 11th victory for Juve in its past 13 games and means it remains within striking distance of Inter in the title race.

The two are set to meet at San Siro on 5 February (AEDT), but before that Juve must navigate games against Lecce and Empoli to ensure it keeps on Inter’s coat tails ahead of the showdown in Milan.
