Dominating the ball possession and finding the goal with ease, Fiorentina returned to the top of Serie A with a convincing 4-1 win over promoted Frosinone Sunday. With Italian Premier Matteo Renzi cheering his home club on, Fiorentina opened up a 4-0 lead by halftime with goals from Ante Rebic, Gonzalo Rodriguez, Khouma Babacar and Mario Suarez. Fiorentina also hit the goalframe twice before Alessandro Frara pulled one back for Frosinone three minutes from the end. Fiorentina is level on points with Inter Milan but holds the edge on goal difference. The Tuscan squad has won eight of 11 matches and taken two straight after losing to Napoli and Roma the past two weekends. Napoli missed a chance to make it a three-way tie at the top with a 0-0 draw at Genoa, ending the southern club's five-match winning streak. Napoli created numerous scoring chances but couldn't find a way past Genoa goalkeeper Mattia Perin. Inter edged Roma 1-0 Saturday, leaving the Giallorossi one point behind. Also Sunday, Bologna beat Atalanta 3-0 in coach Roberto Donadoni's debut. Carpi vs. Hellas Verona and Udinese vs. Sassuolo both finished 0-0. Napoli is two points back in fourth and surprising Sassuolo is five points behind in fifth. Kone treble lifts Everton Arouna Kone grabbed a hat trick as Everton piled on the English Premier League relegation worries for Sam Allardyce's Sunderland with a 6-2 demolition job at Goodison Park Sunday. In the day's other match, Ronald Koeman's Southampton climbed to seventh in the table after first-half goals from Steven Davis and Graziano Pelle secured a 2-0 home win over south-coast rivals Bournemouth. Everton was 2-0 up inside 31 minutes against Sunderland thanks to Kone and Spanish forward Gerard Deulofeu. Kone sent a looping ball over the defence for Deulofeu to score the opener and the Ivory Coast international added a second goal following a one-two with strike partner Romelu Lukaku on the edge of the box. Jermain Defoe inspired a Sunderland rally, volleying their first goal in stoppage time before playing a part in Steven Fletcher's headed equalizer five minutes after the break. The visitors, however, were always vulnerable to the counter attack and Everton made it 3-2 when Sebastian Coates prodded a right-wing cross from Deulofeu into his own net. Deulofeu also set up the fourth for Lukaku, with the Belgian rounding goalkeeper Costel Pantilimon to score. Another Everton counter-attack led to Kone planting the ball into the net with his left foot in the 62nd minute before the Ivorian completed the rout with a close-range header following a centre with the outside of his left boot from Lukaku. Everton's victory lifted it to ninth with 16 points from 11 games while Sunderland remained second from bottom on six points. Southampton has 17 points, moving above Liverpool on goal difference.
