'Greb was my sparring partner once. He was the fastest thing I ever saw in action. Hitting him is one of life's most difficult jobs, because he's never set for a second, never comes at you the same way twice, never does anything in ring warfare which can be called orthodox. He's always doing the unexpected and because he does, he's one of those phantom targets which you can hit more through luck than through the use of skill.'
