Federico Dimarco scored the only goal as Inter Milan continued their perfect start to the Serie A season with a 1-0 win at basement team Empoli on Sunday.

Rafael Leao ended a difficult week with the only goal in Saturday's 1-0 win over Verona which drew AC Milan level with Serie A leaders Inter Milan, while Juventus fell to their first defeat of the season, 4-2 at Sassuolo.

AC Milan's match with Verona was delayed by 25 minutes on Saturday after a sudden hailstorm briefly left the pitch unplayable. Stefano Pioli's Milan were due to open this weekend's round of matches in Italy's top flight at 1300 GMT but kick-off was pushed back until 1325 GMT.

Inter Milan and Juventus are renewing an old Serie A title rivalry as Italy's two most widely supported clubs head into a busy week leading the way. Top of the league with a perfect 12 points, Inter are two in front of second-placed Juve ahead of their trip to pointless and goalless Empoli, which will be followed up on Wednesday with the visit of Sassuolo.

Stefano Pioli insisted on Monday that AC Milan have turned their attentions to the Champions League opener with Newcastle United after local derby humiliation at the weekend.

Inter Milan laid down an early title marker on Saturday by handing out a 5-1 derby hammering to AC Milan and going it alone at the Serie A summit. Four wins from their opening four matches have Inter leading the pack with a perfect 12 points, two ahead of their other fierce rivals Juventus who earlier beat Lazio 3-1.

Dusan Vlahovic shot Juventus temporarily top of Serie A on Saturday as the Serbia striker scored twice in a convincing 3-1 win over Lazio. Goals in each half from Vlahovic and another in the 26th minute from strike partner Federico Chiesa at the Allianz Stadium pushed Juve a point ahead of both Milan clubs before the derby which kicks off later.
