Barcelona paid 105 million euros for Ousmane Dembele with a further 40 million more due to Borussia Dortmund in variable.
The German club will only pocket that cash, though, if certain criteria is met.
Dortmund will received 10 million more once Dembele plays 50 official mathces for Barcelona -- and it doesn't matter when.
They will also get a further 10 million if Barça qualify for the Champions League as little as just one time in the next five seasons.
It's almost certain, then, that they will get another 20 million euros for the France international.
It's not clear how the other 20 million is spread out but it's based on player and team performance, with one of the clauses thought to be if Dembele wins the Ballon d'Or.
Dembele is now training with Barcelona and could make his debut in the Catalan derby against Espanyol next weekend.
