Eugenie Bouchard follows the same ritual Iga Swiatek does as they both listen to the same song always before matches.
Swiatek made a habit to listen to music when she was walking out to the court as a way to prepare herself for matches. Eugenie Bouchard confirmed in a recent podcast appearance that she does the same thing and her song of choice is Danza Kuduro.
"I listen to the same song right before walking on the court: Danza Kuduro."
It's nothing unusual and athletes have been doing that for a long time.
