Tim Tszyu has leaned on his father for tips but knows not even the great Kostya can help when he enters the ring for his much-anticipated US boxing debut on Sunday.
Tszyu (20-0, 15KO) takes on former US Olympic star Terrell Gausha (22-2-1, 11KO) in a super-welterweight world title eliminator in Minnesota, knowing victory is non-negotiable.
