In just three weeks, former WBA heavyweight champion Nikolai Valuev (46-1, 34 KOs) will return to action for the first time since losing his title to Ruslan Chagaev. It has been a summer of changes for the Russian Giant, who has parted company with long-time coach Manuel Gabrielian and appointed Alexander Zimin instead. We caught up with the 59-year-old Russian, who weighs some 100 kilos less than his new fighter, ahead of the clash with unbeaten Canadian Jean-Francois Bergeron. Zimin vowed he will not just help Valuev to win back his title but also teach him how to box attractively. [details]
