Inter Milan 7-0 Sassuolo

Dani Osvaldo was Southampton's record signing when he joined for £15m in 2013

Southampton loanee Dani Osvaldo scored his first two goals for Inter Milan as they routed 10-man Sassuolo 7-0 for the second successive season in Serie A.

A year after winning at Sassuolo by the same score, Inter picked up their first league win of the season.

Argentine striker Mauro Icardi scored a hat-trick with Mateo Kovacic and Fredy Guarin also on target.

The visitors had striker Domenico Berardi sent off for an elbow with the score at 5-0.

Italy striker Osvaldo, 28, cost the Saints £15m a year ago but only played 13 times and, after spending some of last season on loan at Juventus, joined Inter for a season in the summer.

Inter allowed Algeria midfielder Saphir Taider, 22, to move to Southampton on a season-long loan in exchange.

Elsewhere in Serie A, Rafael Benitez's Napoli lost 1-0 at home to Chievo after Gonzalo Higuain missed a first-half penalty and Maxi Lopez struck early in the second half for the visitors.
