The winger was given his marching orders late on for dissent after centre-back Ronald Araujo had been shown a red card for a foul on Javier Hernandez.
It looked a harsh call by the referee and certainly angered Dembele who approached the match official. The ref has now confirmed what happened between the pair.

Ernesto Valverde seemed pretty bemused by the whole thing afterwards. He explained that it’s difficult enough to get much out of Dembele in Spanish.

Yet the sending off means Dembele will miss Barcelona’s next game against Eibar and could face an extended ban that would rule him out of El Clasico too.
