Antetokounmpo is in Athens to present his Nike Air Zoom Freak 1 signature shoe, which will go on sale in August.
He will also attend a 3x3 tournament he sponsors. The tournament will be played on three different Athens courts, with the finals held Saturday near his Athens home, where he first played basketball.
One of the courts has been decorated by a young Greek street artist with a giant image of a dunking Antetokounmpo and God touching him with his finger in the manner of Michelangelo's famous ceiling mural in the Vatican's Sistine Chapel.
Earlier Friday, during the shoe presentation, Antetokounmpo mused about his journey from the Greek-born child of Nigerian immigrants to him and his brothers being the only black kids among 300 students to becoming the first European basketball player to win NBA MVP.
He credited his hard work and great support system in his family, girlfriend and agent, as well as his self-belief.
