Rafael Leao marked his 100th Serie A appearance in style with a derby double to help Milan beat Inter 3-2 at San Siro.

The Portuguese winger added an assist into the bargain as he proved to be the class act on display, having stayed at Milan amid recent interest from Chelsea.

Leao's efforts allowed Milan to score a second successive league derby win over their city rivals, with whom they share the famous stadium. It is the first time they have achieved this since first time since the 2010-11 season, when Milan won their first two league derbies under Massimiliano Allegri.

Olivier Giroud also scored as Scudetto holders Milan took the Derby della Madonnina honours, with Marcelo Brozovic and Edin Dzeko getting the goals for Inter.

Milan's defence splintered in the 21st minute to allow Brozovic a clear run on goal, with the midfielder taking on a throughball from Joaquin Correa and slotting into the bottom-left corner.

Eight minutes later, Leao came up with Milan's equaliser, a left-footed shot that arrowed across Handanovic, who got a fingertip to the ball but could not prevent it finding the right corner.

Sandro Tonali, Theo Hernandez, Charles De Ketelaere and Giroud threatened as Milan stepped up their game before half-time, gaining the upper hand.

It was Giroud who put them ahead in the 54th minute, with Leao's cross from close to the left touchline finding the French striker who send a bobbling shot across Handanovic and into the net. The goalkeeper should have done better.

Inter's defence could hang their heads in shame at the defending that allowed Leao to saunter through to fire his second and Milan's third goal in the 60th minute. The forward's nimble footwork was impressive, but the absence of a tackle was embarrassing.

There was a lifeline for the Nerazzurri when Dzeko cracked in Matteo Darmian's low centre, and Milan goalkeeper Mike Maignan kicked away another shot from the Bosnian as Inter searched in vain for an equaliser.
