Leon Marchand said he had goosebumps after romping to France's first Olympic swimming gold since 2012 in front of a packed and raucous Paris crowd on Sunday.
Marchand obliterated the rest of the field in the 400m individual medley final in clocking 4mins 02.95secs, nearly six seconds clear of Japan's Tomoyuki Matsushita in second, with American Carson Foster third.
