I genuinely don't think the Doku incident is anything like the Trossard one, Doku literally knocks the ball back to where the free kick is supposed to be taken from.
Tross had just smashed into Bernardo, which was a daft challenge to begin with (so subconsciously he was surely expecting a whistle), and then boots the ball away - and no, I don't think he was genuinely trying to play Martinelli in. Oliver is a cunt, but this was nuts from Trossard.
