You play football with your headApr 27, 2015
"This weekend I turned 68. That is a special age for me, because when you add the numbers you get 14. So if this will not be a good year then even I don't know anymore."
"Last week's Champions League was very interesting. Especially if you work at Ajax in a time when the next step has to be taken. For example Bayern München against FC Porto. Porto should be at their best 3-1 up and an opponent that has to attack. But they were 4-0 behind after half 'n hour."
"When you lose like that in the first half hour it has to be because of the pressure. There must have been players at Porto that could not cope with it. And Bayern sensed that and took advantage."
"If you compare that (Porto's defeat) to Atlético Madrid I can really enjoy that team. They not only can play good football, they also play passionately and with their heart. It starts with their coach and every time Atlético manages to make it very difficult for their opponents, even Real Madrid. Atlético are mentally on a high level, and they manage to do keep that level up for every match."
"That mental toughness is an essential part of performing at the highest level. No matter how talented you are, if you don't have mental toughness, you will have serious problems. Whether you are a footballer, a golfer or a swimmer."
"I have said it before, you play football with your head. You can be technically and tactically gifted and skilled, but if things in your head are not right, you are going to have a problem."
