Well at least we know that Potter is much too shit to be of interest to Spurs after that shit show second half. What foreign manager would tell his captain to make sure that he got himself sent off when his team were 1-0 up? Naive in the extreme, looks like we are stuck with the nerd
Chelsea gave Englishman Fat Frank a go, the next best thing. After a good season playing the international quality of Mount and Reece-James plus their galaxy of stars, when they added a further £225m worth of talent, he was showed up to be shit. Tuchel turned that squad into a winning machine in a week.
The same as with players, when the global game is a rich EPL club’s oyster, recruit the best coaches from overseas.
Rodgers and Moyes the honourable exceptions from these isles.
Lots of people have witnessed about the English coaching education system being very poor (probably improved in recent years).
Apart from the courses being quite poor, you can also snooze your way through them if you have a "name". You dont have to really prove yourself in any way, and plenty of former great players think there's nothing to learn... and then they end up like Neville at Valencia, Scholes (Oxford) or Shearer (Newcastle) and so on. Compare that to the Dutch model where even elite players need a two year internship in a youth organisation before they get their badges.
People like Potter and Rodgers learnt most of their stuff abroad. Both of them go/used to go to Spain or Portugal for about a month every year to actually learn something. The whole English coaching culture was stuck in some distant past for a very long time but at least the situation looks better now than ten years ago or so.
