Ousmane Dembele's transfer to Barcelona is "on its way", but the deal is not yet done.

That was the declaration of Borussia Dortmund chief executive officer Hans-Joachim Watzke as the Bundesliga club prepared to offload one of its prized assets for a deal reported to be worth up to €150million.

"The possible transfer from Ousmane Dembele is on its way, but the path is not yet over," said Watzke.
