Perfect! BVB gets offensive weapon Dembelé!
He could have gone to (almost) any club in the world. But he wanted to go to Dortmund. Only to Dortmund (kicker was reporting already). Now this transfer is written in stone: Ousmane Dembelé (18) switches from Stade Rennes to BVB. The both-feet, fast, dribbling-potent attacker, in France already seen as the biggest talent since Thierry Henry, signed a contract with the Bundesliga runnerup until 2021 without a release clause. The transfer fee is said to be around 15 mil.€ as far as kicker knows. Dembelé is the 2nd incoming transfer for Dortmund after Mikel Merino (19, midfield, Osasuna).
I would guess the adjectives i used to describe Dembelé are non-existant in English, but I don´t know if
ambidextrous(?) is the right word for someone who uses both feet. You understand what i mean. I looked out if he is a right of left-footer. I checked the following video for highlights:
In the first minutes, i got the feeling, he is more of a natural left-footer, as he is really dribbling with pace and using the left foot without holding back or anything. Although you see the same with his right foot, also, just not as much as with the left foot in this video, so i assumed he is a leftie. Until at 3:50 or smth, he takes a penalty with the right foot. Either he really uses both feet alike or i don´t know.
(Former World Champ Andreas Brehme, from FC Kaiserslautern, Bayern Munich, Inter Milan,.. did this also, he was a LB, who brough in beautiful crosses with his left foot, but he shot penalties with his right foot.)
