I keep on thinking that the Turkish handsome assistant coach, Ferhat Akbaş, was keen to get out early from the current JPN team. He must have seen something from within.
I listened to his interview with the podcast freeball. He said he enjoys working in the Japanese team but they want him to work there full time, even during the club season, at least the few years before Tokyo. He took an offer in Romania to coach a club so he has to leave there. And he thinks that's better for his career.
