Inter Milan beat city rivals AC Milan 3-0 to extend their lead at the top of Serie A as Lautaro Martinez scored a double, with Romelu Lukaku also on target.
Inter opened up a four-point lead over their second-placed opponents as Antonio Conte’s side target a first league title since their unprecedented treble under Jose Mourinho in 2010.
Lukaku was on top form, the Belgian playing a role in Martinez’s two goals on five and 57 minutes before scoring his 17th goal in the league this season to move top of the Serie A scorers’ chart.
Milan, chasing a first Scudetto since 2011, fell to back-to-back Serie A losses for the first time this season, with their title push suffering another blow with a fourth defeat in eight league games.
The match was played behind closed doors at the San Siro because of the coronavirus pandemic, but that did not stop thousands of fans gathering outside the stadium for the final Milan derby of the season.
It was the third derby of the season, with Milan winning the first 2-1 in the league.
Inter won a fiery Italian Cup quarter-final by the same scoreline, a game overshadowed by Zlatan Ibrahimovic and Lukaku squaring off and trading insults, with the Swede later sent off.
And Conte’s side came out firing with Lukaku powering down the right flank.
