Borussia Dortmund CEO Hans-Joachim Watzke has branded as 'fake news' reports that Ousmane Dembele's injury means Barcelona will pay the German club €10 million less in bonuses.

Dembele, 20, cost Barcelona €105 million, and up to a further 42m in bonuses, when he left Dortmund last month after signing a five-year contract with the Spanish giants.

However, the French international winger is expected to miss three and a half months after tearing a thigh muscle which saw him go under the knife on Tuesday.

Spanish sports daily Marca claim Dortmund can write off at least a quarter of the expected bonus due to Dembele's injury, but Watzke dismissed the report.
