Former American competitive swimmer Michael Phelps said Sunday that fellow United States athlete Caeleb Dressel has an “impressive” track record and the opportunity to achieve “something special” in Tokyo 2020.

He also praised Team USA veteran swimmer Chase Kalisz’s first American gold medal achieved in the 400 meters individual medley, as well as underdog Tunisian teenager Ahmed Hafnaoui’s shock win in the men’s 400m freestyle.

The American swimming legend retired after the Rio 2016 Games, but is attending Tokyo 2020 as a sports commentator. EFE
