Borussia Dortmund has confirmed that Christian Pulisic has signed with Chelsea on a €64 million ($72 million) transfer. Pulisic will be loaned back to Dortmund for the remainder of the season and join Chelsea in the summer.

“It was always Christian’s dream to play in the Premier League,” said BVB’s sporting director, Michael Zorc. “That certainly has to do with his American background, and as a result we were unable to extend his contract. Against this background, we have decided to accept an extremely lucrative bid by Chelsea, given the low contract maturity.

“Christian Pulisic is a character perfect player. I am sure that in the coming months he will do everything in his power to bring his high quality to the team and to achieve his sporting goals with his teammates at Borussia Dortmund.”

Speaking to Chelsea’s website, Pulisic said it was “a privilege to have signed for such a legendary club and I look forward to working hard towards being a contributor to their team of world class players.”

Pulisic becomes the most expensive American player in history, with Chelsea director Marina Granovskaia stating her delight to have signed “one of Europe’s most sought-after young players.”
