Milan: A superb scissor-kick from Radja Nainggolan helped secure the points as Roma closed the gap on Serie A leaders Juventus to just a point on Sunday after a 1-0 defeat of 10-man Genoa.

Gian Piero Gasperini’s high-flyers welcomed Roma looking for their seventh win in 10 games but the visitors were given a huge incentive after Sampdoria held Juventus to a 1-1 draw in Turin.

Roma were given a boost on the half hour when goalkeeper Matti Perin was issued a straight red card for a challenge on Nainggolan in the area.

Although replacement Eugenio Lamanna did well to stop Adem Ljajic’s resulting spot-kick on what was the ‘keeper’s Serie A debut, Roma’s advantage would eventually tell.

Nainggolan found himself in space five minutes before half-time and produced a fine piece of mid-air wizardry to fire Maicon’s delivery past a helpless Lamanna.

The result has given a huge boost to Rudi Garcia’s men only days after their failure to reach the last 16 of the Champions League following a 2-0 home defeat to Manchester City.

“I’m happy we took the opportunity to cut the gap on Juventus to one point,” Garcia told Sky Sport.

“We should have scored another goal after the break to ease the pressure. Playing here is tough, all teams will find it hard against Genoa at the Marassi.”

Gasperini - who was informed during half-time he would be sent to the stands for dissent - insisted his side emerged with “even more belief” about their qualities.

“Playing three-quarters of the game a man down weighed heavily on us. It would have been an altogether different game otherwise,” said Gasperini.

“But this has left me with even more belief about our qualities.”

In Sunday’s late game, goals by Jeremy Menez and Giacomo Bonaventura secured a precious 2-0 win for Milan over Napoli that moved Filippo Inzaghi’s side up to sixth.

“We’re delighted with the win, it’s given us back our enthusiasm,” Menez told Mediaset Premium.

“These three points will serve us well in the future. We’ve beaten a great Napoli side, we have to keep going like this.”

Menez expertly skipped past French defender Kalidou Koulibaly in the sixth minute to send an angled strike past Rafael at the keeper’s far post.
