Borussia Dortmund continued their summer spending spree by snapping up Turkey's highly rated teenage international winger Emre Mor from Danish side FC Nordsjaelland on Tuesday.

The 18-year-old has emerged as one of Turkey's great hopes as they head into the European Championships in France.

Mor said on Instagram that he was "very honoured and happy to be part of the Dortmund family and to play in one of the biggest clubs in the world."

The winger has lived all his life in Denmark and only received Turkish citizenship earlier this year, following intervention by Turkey coach Fatih Terim.

"It's great that we can attract talents with Emre's qualities to our academies, and then bring them on to the biggest clubs in Europe," FC Nordsjaelland sporting director Carsten Jensen said.

"This agreement will stand as the best in the club's history, and is obviously unique, because otherwise we would not have chosen to sell him before the European Championship finals.".

The clubs agreed not to disclose the fee for Mor.

Dortmund have made a flurry of signings in recent weeks, with Mor becoming the fifth new recruit over the summer.
