Wallis Debourou was born in 1993 in a town based in the outskirt of Paris (France), called Orsay. The outskirts of Paris is known for producing some of the very best soccer players in the world: Thierry Henry, Kylian M’bappé, Paul Pogba, or Zinédine Zidane are all from this type of background. A couple years after his birth, Wallis moved back to Benin with his parents where he started school along with playing unorganized street / playground soccer and later on, organized soccer when he joined the U12 Benin National Team.

Wallis won multiple MVP awards as a youth PSG player and decided to move to the United States in 2009 to play for the New York Red bulls after being scouted in Paris.
