American 17-year-old Christian Pulisic made his professional debut for Borussia Dortmund on Saturday.

Pulisic had scored in a friendly at Union Berlin last Sunday, and manager Thomas Tuchel rewarded him by putting him on for Adrian Ramos in the 68th minute of the Bundesliga clash.

"He has shown the courage from training also in the match today," Tuchel said after the game.

Pulisic, who has played for the United States under-15 and under-17 teams, signed with Dortmund a year ago and was added to first-team training at the beginning of this month.

"I've worked very hard for this day," Pulisic said.
