I may have some grey hairs, but one thing's for sure, I'd have plenty more if I'd gone into management.
Managers have to make tough decisions and Croatia's Jozic Mirko had a big call to make and it didn't come off.
He opted for experience and stuck by many of the players who finished third at France 98, but ageing players can mean tired legs - particularly in the heat of Japan.
But for a red card in the opening match they could have given Mexico a greater run for their money and they showed what they could have done when they came from behind to beat Italy.
Maybe it was that effort, maybe it was their age, but something caught up with Mirko's men and the wheels came off in the final match when a win would have seen them go through.
Never mind the grey hairs, such a frustrating finish is enough to make you pull your hair out.
