Napoli outclassed Sassuolo in a 2-0 victory at the Mapei Stadium, with first-half goals from two men bang in form ensuring that the table toppers have a lead that has proven unassailable in previous Serie A editions awarding three points for a win.
Sassuolo had built a reputation as giant killers this season, most notably defying the odds to beat both Atalanta and AC Milan.
But runaway leaders Napoli are a different proposition entirely, and proved it in the 12th minute, when Georgian sensation Khvicha Kvaratskhelia once more stole the spotlight.
After continuing to dictate play, Napoli had a two-goal lead just 20 minutes later via another of their in-form aces.
This time it was Serie A’s current top gun Victor Osimhen who made his mark, when he chased a hopeful ball into the channel before unleashing a surprise strike from a tight angle.
Sassuolo thought they had found a route back into the game just before the break, when Armand Laurienté smartly converted, but VAR intervened and ruled out the goal for offside, almost certainly spelling the end of any comeback hopes Sassuolo may have had.
The second 45 minutes was played at exhibition pace, as Napoli sauntered to a 20th victory of the season, and it will now require a collapse of unthinkable proportions for Napoli to lose the title now.
