Caeleb Dressel will need to put on a flawless showing to win eight gold medals at the 2020 Tokyo Olympics, Michael Phelps said.
Phelps set that record at the 2008 Olympics in Beijing, while Dressel will head into next year's Games on the back of winning eight medals—six of them gold—at the 2019 World Aquatic Championships in Gwangju, South Korea.
The 23-time Olympic gold medallist told the Associated Press (via ESPN): "If there's someone who doesn't care how hard it's going to be, how hard they're going to have to work, how much pain they're willing to put their body through, we might see it.
