I don't think you should do that in an FA Cup or League Cup game, a friendly game or even a training session, said Slot. It's a weird choice and I have my opinion about it but I prefer to keep that to myself and speak about that with Dom.
There's no VAR so when he gives it, if he had made a mistake, there was not the possibility to correct it, said Slot. From what I've been told, it wasn't a penalty and Dominik played the ball, but I have to see it back to give you my opinion.
