United States international Christian Pulisic's career has no limits, according to Andreas Herzog.
In his first full pro season, the 18-year-old has already become one of the key players in Borussia Dortmund's squad. He has played in 21 of BVB's 25 league games, and featured in every Champions League match, starting six of them including the most recent 4-0 win against Benfica.
"He's already reached a significant level at 18," Former U.S. assistant coach and current U.S. Under-23 coach Herzog told kicker. "He now needs to raise that level year after year, which is not easy."
Pulisic has scored five goals and set up a further nine, drawing widespread praise, first in the United States and in recent weeks also in Germany, where he has been compared to both Henrikh Mkhitaryan and the young Mario Gotze during Gotze's breakthrough years at the Westfalenstadion.
