USA coach Gregg Berhalter is delighted seeing Christian Pulisic prove himself at Chelsea.

Pulisic shone for Chelsea in his first season before injury struck.

"When Christian was moving from Dortmund to Chelsea we knew there was going to be an adaptation period," said Berhalter to Chelsea's Miked Up podcast.

"The Premier League is an extremely fast and physical league, and we knew time would be needed for him to get up to speed. What I really like about how his season unfolded, particularly in the beginning, is that he had to endure adversity to overcome struggle.

"He had to get used to the English game. It took time, and as he did that he came out performing really well, helping the team and scoring goals and being influential. All these things we projected him being able to do took an understandable time period.

"When you go into the injury period he had, it's unfortunate because he was in such good form. The next part of it was him dealing with a serious injury. He was in a lot of pain. It was a difficult injury to come back from quickly although I know the fans wanted him back."
