Inter Milan 4-0 Frosinone

Jonathan Biabiany is in his third spell at Inter

Jonathan Biabiany scored on his first start since August 2014 to set Inter Milan on their way back to the top of Serie A with victory over Frosinone.

The winger, who rejoined Inter this summer, was diagnosed with a heart problem, arrhythmia, last year.

He fired home after a shot was parried and Mauro Icardi tapped in a second.

Inter added two late goals, with Jeison Murillo finishing from Stevan Jovetic's backheeled pass and Marcelo Brozovic driving in a fourth from 18 yards.

Napoli had gone top earlier on Sunday thanks to a 2-0 win at winless Verona, with Lorenzo Insigne and Gonzalo Higuain scoring midway through the second half.

Fiorentina then missed a chance to overtake them at the top. They had to come from 2-0 down to draw 2-2 with Empoli thanks to two goals from Nikola Kalinic.

Torino overtook Atalanta into ninth with a 1-0 win, while mid-table Chievo beat bottom side Carpi 2-1.

Lazio moved up to eighth with a 1-1 draw against Palermo and Udinese went four points clear of the relegation zone after beating Sampdoria 1-0.

Genoa are one of six clubs separated by a point from 11th to 16th thanks to a 2-1 win over Sassuolo. Leonardo Pavoletti scored a 95th-minute winner against his old club as both sides ended with 10 men.
