Christian Mate Pulisic is an American professional footballer who plays as a winger or attacking midfielder for Premier League club Chelsea and the United States national team. Pulisic began his professional career with German club Borussia Dortmund where, after making rapid progress in the team's youth academy, in which he made only 15 appearances at a young age, he was promoted to the senior squad in 2016 at the age of 17. He played little in his first season at the club, but his participation increased significantly in the subsequent campaign, where he was a mainstay of the Dortmund side that won the 2016-17 DFB Pokal Championship. In 2018, he finished second in the opening of the Copa Cup, awarded to the best player under 21. In January 2019, Pulisic joined Chelsea for a $73 million transfer fee, making him the most expensive North American player of all time, and began playing for the club in the 2019-2020 season. Pulisic scored 15 goals in 36 games as an American international.
