Borussia Dortmund have described Jadon Sancho as “one of the most exciting players in Europe” after the England Under-19 international signed a contract extension with the German club until 2022.

Sancho, who left Manchester City last summer for £8m in search of first-team football, has enjoyed a spectacular start to his career in the Bundesliga – making 12 appearances last season. The Londoner, 18, has followed that up this season with one goal and seven assists from just 124 minutes of league football and is now in line for a call-up to the England Under-21 side.

“I’m so happy that I chose to come to Dortmund a year ago,” said Sancho in a statement. “Everything I was hoping for has come true: this city loves football like no other, and at BVB young players get regular playing time. I can really make outstanding progress here. I’m happy, delighted and proud to be part of this team. We’re building something amazing.”

Sancho was voted the player of the tournament at last year’s European Under-17 Championship but missed the final few matches of the Under-17 World Cup in India after he was recalled by his club. He began his career at Watford before moving to City in March 2015.

“Jadon Sancho is without doubt one of the most exciting players in Europe,’’ said Dortmund’s sporting director Michael Zorc. “This contract extension acknowledges the extremely positive development he’s made.’’

Despite his excellent start, however, Sancho was surprisingly overlooked as one of the nominees for the 2018 Golden Boy award.
