Speaking to reporters in his post-match press conference, the Dutch coach said: "I think what the team showed today, the character they showed, that's also what Robbo showed. Sometimes if you get a kick like this, two studs on a knee, that can hurt for a few minutes. Then, if you just keep on running, it gets better and better and that's what we were hoping for.
"Not least because I only had one defender on the bench, who was not a left full-back as well. So, we were hoping he was managing to come through it and I think he did quite well, but the moment I noticed he wasn't completely himself was the one time they put the ball in behind and he started running."
He added: "He was just able to head it back to Ali [Alisson Becker], but I thought, 'OK, let's see how this continues' and I think it was quite quickly afterwards where he conceded the red card. Nothing to blame on him, [it was] character that he wanted to continue because he got quite a hard knock on his knee with two studs. Unfortunately, it led to a red card that was a deserved red card."
