The midfielder was dragged off on 28 minutes by a furious De Boer.
De Boer stated: “This morning we talked about it, that he had to play simple and on the Bologna goal he did not do that. We already talked about this and he makes the same mistakes often.
“We cannot accept that from players when we've told them many times already. I told him this morning, so if he doesn't want to listen, then what can I do? It's not the first time we've discussed it."
Gabriel 'Gabigol' Barbosa was given his debut late on.
“It wasn't easy to come on with all that pressure of a 1-1 situation, but in my view he did pretty well. We know he can play better. This is only his first appearance."
