Coach Bob Bowman hails 'perfect' Leon Marchand as Frenchman claims fourth gold

Leon Marchand's coach Bob Bowman said the French swimmer handled the pressure of performing and delivering on home turf in the Olympics perfectly after the 22-year-old sensationally swept the gold medals in all four events he entered at the Paris Games.

Marchand won the 400m IM, then the 200m butterfly and 200m breaststroke on the same night, and finally the 200m IM on Friday to earn hero status in France as he shot to the top of the medal charts among individual athletes.
