It's everyone's fault but Dembeles. We need a elite coaches, the best in the world to teach Dembele how to complete short passes and trap the ball under his feet.
Plenty of successful players were injury ridden during the early stages of their career, injuries didn't suddenly cause them to forget how to pass and control a ball. They still possessed their technique and passing ability (Robben for example).
Dembele never had the ability to go elite. Once again, there were plenty of people here being skeptical of his technique before we signed him. Cal back to all the "he looks raw, ball looks loose with him" comments before we signed him.
If we had pep instead of valverde, Pep would have signed him off to some other team after a single season in Barcelona.
You're not supposed to learn the basics of football at the age of fucking 20 at Barcelona.
He worked in Dortmund for Tuchel because the Bundesliga is a league with shit loads of open space benefiting speed merchants with poor technical ability like Dembele and Werner.
