Arnold not at his best beat Sergio who was at his best in 1972.
Enough said.
It was always an eipic battle, but in the '72 Olympia , in my judgement, Sergio was clearly better.
He was thicker, fuller, better thigh sweep and V taper. Sergio beat Arnold badly in the frontal crab most muscular that that Olympia.
The other time was the 1970 Mr World. Sergio looked like he was on a whole other level of development that show.
