United States under-17 goalkeeper Will Pulisic will join his cousin at Borussia Dortmund next season, he announced on Tuesday.

Christian Pulisic has broken into the Dortmund first team, making six appearances since January, including in last week's Europa League win over Tottenham.

His cousin Will Pulisic committed to play at Duke in February, but will postpone that for a year to train with Dortmund's youth teams, he said on Twitter:

Excited to announce I'll be playing for Borussia Dortmund for the 2016-17 season and will postpone my career at Duke for another year #BVB�� - Will Pulisic (@willpulisic) March 21, 2016

He will retain his college eligibility unless he signs a professional contract
