Inter Milan stretched their lead at the top of Serie A to 15 points after they earned a 2-1 win over Genoa at San Siro.

After a slow opening spell, the home side soon clicked into gear and established a two-goal lead by the 38th minute through Kristjan Asllani’s strike and Alexis Sanchez’s penalty.

Inter looked like they would go on to cruise to victory but they were soon forced to increase their concentration levels when Johan Vasquez pulled a goal back for the away team nine minutes after half-time.

Vitinha then thought he levelled things up for Genoa but the offside flag saved Inter, who held on to stretch their winning run in Serie A to nine games.

Inter were frustrated through the opening quarter with the hosts coming closest when Nicolo Barella pounced on Henrikh Mkhitaryan’s long ball but guided over the crossbar.

Genoa came close to breaking the deadlock after Stefano Sabelli’s cross was powerfully headed towards goal by Mateo Retegui but Yann Sommer saved. The rebound fell into the path of Albert Gudmundsson who diverted wide.

Inter had the breakthrough on the half-hour mark when Sanchez’s through ball found Asllani, who smashed emphatically into the roof of the net to make it 1-0.

The hosts had a chance to double their lead when Lautaro Martinez picked out Barella, who was adjudged to have been fouled inside the area by Morten Frendrup and a spot-kick was awarded.

Sanchez stepped up for the penalty and powered into the right side of the net, sending the goalkeeper the wrong way.

Inter were smelling blood and could have had three when Mkhitaryan raced through on goal and let fly only to see his goalbound shot blocked by Johan Vasquez.

Genoa had a route back into the game nine minutes after the break after Stefan de Vrij’s defensive header looped straight into the path of Vasquez who arrowed a volley into the bottom right corner.

The visitors thought they had an equaliser when Vitinha cut inside and picked out the bottom corner but the assistant referee’s offside flag cut celebrations short with 20 minutes to go.

Genoa came close once again but Tottenham loanee Djed Spence’s cross was glanced wide by Retegui and Inter held their nerve to edge closer to the Serie A title.
