Milan moved five points clear at the Serie A summit with a 1-0 win over Empoli, as Pierre Kalulu's stunner settled a cagey match at San Siro.

French defender Kalulu netted a superb first-half opener for the Rossoneri, who restricted Empoli to just one shot in the first 45 minutes during a dominant showing.

Although the visitors improved after the break, they struggled to create clear-cut chances against the title challengers, as Milan took an important three points from a tight affair.

The result gave Stefano Pioli's men breathing space at the top of Serie A, while Empoli remain without a win in 2022.

Milan were denied an early lead when Guglielmo Vicario saved well from Alessandro Florenzi's curling effort, and they again went close when the ball ricocheted off Sandro Tonali and rolled wide.

But the hosts did hit the front on 19 minutes when Kalulu finished brilliantly from the edge of the area, firing home with his left instep after the ball deflected to him.

However, Mike Maignan was forced into two stops within five minutes of the restart, turning Sebastiano Luperto's header around the post before punching Nedim Bajrami's goal-bound corner away.

Two tame Junior Messias shots, both drawing routine saves from Vicario, were the sum of Milan's efforts for much of a dull second half in which chances were at a premium.

However, Milan's solid defensive display was enough to hand them the victory and strengthen their position in one of Europe's closest title races.
