U.S. youngster Christian Pulisic trains alongside Borussia Dortmund stars

United States youth international Christian Pulisic trained for the first time with Borussia Dortmund's first team this week, with coach Jurgen Klopp calling him "a great footballer."

Pulisic, 16, is still waiting for his playing licence from the German Football Association and until then is limited to only training.

Between stints with the U.S. under-17 side, he has been improving his skills with Dortmund's under-17 and under-19 teams, and this week was called up to train with the club's first team.

"We were missing his position and that's why we called him up. He did a good job," Klopp told reporters.

Pulisic is part of a generation of players in BVB's youth academy that have received plenty of public attention in recent weeks.

Youngsters like Felix Passlack and Dzenis Burnic joined Dortmund for their winter training camp in January, and Bild has already compared the former to Mario Gotze, who also came through the club's youth academy.

"Pulisic is part of that generation," Klopp said. "He's a great footballer, an attacking midfielder. He can kick the ball around really well. And in a very intense training session with narrow spaces, he did not stand out in a negative way. This is a real sign of quality."

The Dortmund boss, however, insisted that the club will manage their youngsters carefully.

"That's important for their development. That might not be possible everywhere -- as you can see with [Martin] Odegaard [at Real Madrid]," he said. "But we will do all we can to allow the lads the time they need in spite of the great talent and the great quality they already have."
