Hiddink believes Ten Hag's reliance on his personal circle was a significant misstep. According to him, surrounding oneself with too many familiar faces can create an isolating environment that hinders integration into a new club’s culture.
“Everyone does it in their own way, but I was surprised at how many confidants Erik gathered around him,” he told Voetbal Primeur.
“Then you end up on an island, which makes it more difficult to integrate into the culture of your new club and is watched with suspicion. I always took one assistant abroad with me, with whom I could map out things in the field of football. I therefore opted for local trainers and supervisors. People who knew the club or the country well.
“You play a role in how you are judged. Sometimes approach it with a wink. I mean, we are talking about football, not about war and peace. You should not respond to force that comes your way with force. Then it will explode somewhere.”
