At his pre-match press conference, the Dutch coach told reporters: "It's difficult to say what makes him a special manager if you don't work with him on a daily basis but he is, that is clear. Bottom of the league when he took over, didn't spend much, mainly the same players, and they only lost in the final of the Europa League.
"What makes him special is hard because I haven't faced him or worked with him but what might be the situation is he worked with incredible managers in the past and played at the highest levels. So he also knows and understands what players feel at certain moments. That all contributes to what a manager he is. The best way to find out what makes him special is to ask the players he has worked with."
