Bulgarian sekiwake Kotooshu continued to leave a trail of destruction in his wake at the Autumn Grand Sumo Tournament as he bumped out Kyokushuzan on Sunday to remain the sole leader with a perfect 8-0 record.

Kotooshu appeared nervous at the face off but faced little resistance from Kyokushuzan (4-4) and with a firm grip on his belt, he quickly worked the Mongolian maegashira to the edge of the ring before ushering him over the straw bales at Tokyo's Ryogoku Kokugikan.

Kotooshu stayed one win clear of grand champion Asashoryu with a week of the 15-day tournament left to go but he sensibly played down his chances of becoming the first European to win the Emperor's Cup.
