Borussia Dortmund boss Thomas Tuchel has branded Ousmane Dembele "extraordinary" and backed the French youngster to continue to impress with the German outfit.

Dortmund won the race to sign teenage attacker Dembele from Rennes in the summer transfer window, pipping the likes of Real Madrid and Barcelona in the process.

The 19-year-old has scored one goal and provided two assists in six Bundesliga appearances this season and Tuchel is confident that the Frenchman will continue to improve throughout the campaign.

"Of course we love his dribbling, we love his bravery, we love his pace, his control on the ball. We know a lot of the facets of his game from the training," Tuchel told reporters.

"Ousmane is a player who brilliantly combines dribbling passing and making space to a very high level. That's extraordinary. It's a great pleasure to work with him and it's a big challenge for him to face everything he has and still be the level he is.

"We hope that we can provide him the environment he needs to develop in the way he wants and that he is a great assistance for us also."

Dortmund will return to Bundesliga action at home to Hertha Berlin on Friday night.
