Milan: Napoli clung to top spot in Serie A with a 2-0 win over tailenders Benevento on Sunday, after Gonzalo Higuain hit a rapid hat-trick and Sami Khedira two in three minutes as champions Juventus piled on the pressure in the title chase with a 7-0 win over Sassuolo.

Juventus were 4-0 up by half-time after Alex Sandro opened the

"Many players are beginning to reach their peak."

The only bad news for Juventus was Blaise Matuidi picking up a muscular injury which Allegri said should keep the French international out of the Champions League clash against Tottenham on February 13.

In Naples, Mertens opened the scoring after 20 minutes at neighbouring Benevento with a magnificent lob from a tight angle, but the Belgian limped off with an ankle injury in the final minutes of the game.

Slovak Hamsik doubled their lead just after the break, meeting Jose Callejon's low cross for his 118th goal for the club.

Benevento had a few chances and were even awarded a penalty for a Kalidou Koulibaly tackle, only for it to be revoked by the video assistant referee (VAR) because of an earlier offside.

"We suffered at the start, but then broke the deadlock with a great goal from Dries Mertens," said Napoli skipper Hamsik.

"Once we went 2-0 up, we tried to slow it down a bit and control the game.

"We're not afraid of anyone, as we must only focus on our own results."

Roma back winning: Earlier Roma got back to winning ways to move closer to the Champions League places with Turkish winger Cengiz Under scoring the only goal within the first minute in Verona.

Roma had not won since December 16 but 20-year-old Under got them off the mark early on taking the hosts by surprise to slot in his first Serie A goal.

The visitors held on despite Lorenzo Pellegrini being sent off after 51 minutes for tackling Ryder Matos from behind.

Roma stay fifth but move to within a point of Inter Milan who occupy the final Champions League spot after being held 1-1 by Crotone on Saturday.
