Personal life
Giovanni is the son of former Rangers F.C., Sunderland, Manchester City, New York Red Bulls, and United States player Claudio Reyna, and Danielle Egan, a former member of the United States women's national soccer team. Reyna was born in Sunderland, England while his father was playing for Sunderland. Reyna started his international career by playing with the United States' youth teams, but after impressing with Borussia Dortmund, he attracted interest from the Portuguese, English, and Argentine national teams, all of whom he is eligible to play for. Ultimately, all speculation was put to rest on March 5, 2020, as Sports Illustrated quoted him as saying "I'm aware of the rumors, but it's quite clear for me. I only want to play for the United States. That's my home country." He was named after his father's former Rangers teammate Giovanni van Bronckhorst.
