Higuain fires Napoli

Argentina striker Gonzalo Higuain scored his sixth goal in four consecutive games to secure a precious 1-0 win away to Fiorentina that moved Rafael Benitez's side up to third in Serie A on Sunday.

However Napoli's win was tempered by winger Lorenzo Insigne suffering a suspected knee ligament injury.

A club statement said Insigne, who was forced off in the 25th minute and replaced by Dries Mertens, had suffered a "distortion of the right knee involving the ligaments.

"Tomorrow (Monday) morning he will undergo a scan."

Higuain beat Fiorentina 'keeper Neto with a powerful shot from close range on the hour of a thrilling encounter at the Artemio Franchi stadium, where Mario Gomez saw a late header come off the crossbar as the hosts pressed for a late equaliser.

Higuain took until the eighth game of the season to get off the mark for Napoli, scoring a hattrick in a 6-2 win over Verona.

But he has hit the net in three successive games since to sit on six goals for the season, two behind table-topping teammate Jose Callejon, who saw Juventus striker Carlos Tevez pull level on eight goals with a brace in a 7-0 rout of Parma earlier Sunday.
