He told TNT Sports: "The goal, it’s [a] team [mistake], a player of Twente can dribble through almost the whole pitch, or half the pitch, without stopping. That is not acceptable, we can't give a goal away like this. We have seen, again, you have to keep going for the whole game; once you are 1-0 up you have to keep going and go for the second [goal].”
The Dutchman later told reporters: "I can offer mentality is very good from this team. I saw in many games how high our work rate is, but today I have some criticism. It is not only the team, I have to look in the mirror as well. I am part of it. We have to be more clinical in such situations."
