Martinez double sends Inter top
Lautaro Martinez starred for Inter as his double helped Antonio Conte's side to a 2-1 victory over SPAL and moved the Nerazzurri top of Serie A.
With Juventus having drawn with Sassuolo in Sunday's early fixture, Inter knew a win at San Siro would be enough to leapfrog Maurizio Sarri's men, and it had too much for a struggling SPAL side which is now winless in seven matches.
Martinez spearheaded Inter's attack – picking out the bottom-left corner of Etrit Berisha's goal with supreme accuracy in the 16th minute before doubling his tally with a well-placed header prior to half-time.
Mattia Valoti struck to spark a rejuvenated SPAL performance after the break, yet – despite Martinez squandering two golden chances to round off a hat-trick – Inter held firm to claim top spot.
Romelu Lukaku broke through SPAL's line in the 11th minute, though Berisha did well to rush out and close the angle.
Berisha was beaten five minutes later, however – Martinez gliding forward before directing a low finish across SPAL's goalkeeper.
Lukaku and Marcelo Brozovic both went close as Inter kept up the pressure, but the hosts had their second four minutes before the break, Martinez guiding home Antonio Candreva's excellent first-time cross.
Against the run of play, SPAL pulled themselves back into contention early in the second half as Valoti carved through Inter's defence and slotted in off the left-hand upright.
Alessandro Murgia might have made it 2-2 had he connected well with a looped cross, while Martinez saw a close-range header saved by Berisha before he then failed to beat the goalkeeper when one-on-one soon after.
Matias Vecino's close-range miss buoyed SPAL's resolve, but Andrea Petagna failed to take advantage when the visitors' next chance came his way, while Jasmin Kurtic went close with a rasping long-range strike as Inter held onto the points.
