SUBSTITUTE Stefano Okaka scored with a stunning backheel two minutes from time to give flying AS Roma a 2-1 Serie A win over bottom side Siena yesterday.

Roma went level on points with second-placed AC Milan, who ended a difficult week by labouring to a 1-1 home draw with struggling Livorno.

Both sides moved eight points behind leaders Inter Milan, whose match at Parma was postponed because of snow, although Roma have played a game more.

The little-used Okaka was due to make a loan move to Fulham but was named in yesterday’s squad because four Roma forwards were out injured, including Francesco Totti and Luca Toni.

The 20-year-old entered the fray on the hour after John Arne Riise’s terrific volley put Roma ahead before Simone Vergassola equalised from a tight angle late in the first half.

Okaka made an immediate impact and then found the perfect moment to score his first league goal of the season with a powerful backheel from eight metres out.

Milan could have done with a moment of magic themselves after another lacklustre performance at the San Siro following the previous weekend’s defeat by nine-man Inter and Wednesday’s Italian Cup exit at the hands of Udinese.

Ronaldinho struck a post before David Beckham swung in a cross which goalkeeper Francesco Benussi failed to hold, leaving Massimo Ambrosini to hook the ball home just before the break.

Livorno, whose coach Serse Cosmi resigned last week before changing his mind, equalised eight minutes into the second half when striker Cristiano Lucarelli prodded in Claudio Bellucci’s scuffed shot.

New Juventus caretaker coach Alberto Zaccheroni, who replaced the sacked Ciro Ferrara on Friday, got off to a mixed start with a 1-1 home draw against former club Lazio last night.
