Olunga is a 27-year-old Kenyan professional footballer who is the captain of Kenya's national team Harambee Stars.
His career in football started at the Liberty Sports Academy while still in high school.
Later, he signed with the Kenya Premier League side, Tusker, in 2012.
He was then loaned to Thika United for an additional year before he moved to Gor Mahia in the beginning of the 2015 season.
The next year he joined the Swedish team, Djurgardens IF, on a four- year contract. While playing for the team he was nominated for the Newcomer of the year in Swedish football.
In 2017, Olunga joined Girona FC, La Liga, where he later went on to score a hat-trick during a game that made him both the first Kenyan and first Girona player to score a hat-trick in La liga.
2020 was an equally rewarding year for the star athlete as he was the top scorer in the 2020 Japanese J1 League winning the Golden boot and the J-League 2020 MVP. He is the first Kenyan to win the award.
As of 2021, he plays for Qatar Stars League, Al-Duhail. He has now emerged the top scorer in the 2021 Asian Football Confederation (AFC) Champions League winning the Golden boot.
