The triple gold medallist of the 2015 World Championships did not know how he did it as well, reports Xinhua.
"I don't know. I mean I went out pretty fast, quite easy, came back and I heard everyone cheering. I thought what they are cheering for, as there's no Brazilians in this lane?" said the 21-year-old swimmer.
