Former Dutch coach Aad de Mos feels the current generation are limiting themselves in their development phase.
He wrote for HLN: "In the Netherlands, trainers are created. If they learn their lessons, they get their diploma from the KNVB. A bit like driving a license, I never learned from that. My statement is: As a trainer you are born.
"It's a big handicap that they do not have a helicopter view anymore," continues the former trainer of Ajax and PSV. "In modern football it has changed a lot, but De Boer struggled because he knows only the Ajax method. Many Dutch coaches have a large lack of flexibility and are not creative."
