Ivory Coast striker Salomon Kalou grabbed a hat-trick to steer Hertha Berlin to a 3-1 win at Hanover on Friday and into the top four of the Bundesliga.

The 30-year-old former Chelsea star found the target in the 33rd and 60th minutes before completing his hat-trick with a penalty three minutes from time.

Kalou now has seven goals in the Bundesliga this season.

Japan's Hiroshi Kiyotake scored Hanover's only goal with a 70th-minute spot-kick.
