Peter Bosz's time as Borussia Dortmund manager lasted just half a season back in 2017, but that was long enough to leave the Dutch manager with a good impression of U.S. national team star and new Chelsea signing, Christian Pulisic.
Bosz coached Pulisic during his time with the current Bundesliga champions having joined the club after earning plaudits for guiding a young Ajax side to the Europa League final.
The 55-year-old's time at Westfalenstadion coincided with a difficult period of time for Pulisic, who endured the U.S. national team's failure to qualify for the World Cup in October of 2017.
