Romelu Lukaku and Lautaro Martinez combined to help Inter see off Lazio 3-1 at the San Siro last night and go top of the Serie A standings.
After Milan’s shock 2-0 defeat to Spezia on Saturday, the Nerazzurri were aware that a win over Lazio would put them one point clear of their city rivals.
Lukaku gave Inter the ideal start when he converted a 22nd-minute penalty.
The Belgian struck again on the stroke of half-time when he blasted the ball past Lazio goalkeeper Pepe Reina to hand Inter a 2-0 lead.
