OK here is my view and sorry if I go in a few different directions with this ! The best coaches need to be teaching our best players !!! It is that simple and where you are from should not come into it.
One of the issues that has been discussed is around Heraf. The book fully stops here with Andy Martin. Heraf has worked at a high level for a number of years in the game but now he is in NZ he is all of a sudden a bully but never a mention of anything similar in the past ........ Well I do not buy that. The football culture here in NZ is quiet different than most of the world in my opinion so Andy Martin should have went into detail with Heraf around what what he was coming into.The fact he did not probably tells you he does not understand it himself which is a real worry. Then to allow your technical director to become so invested in the women's team when his job is to overlook the game as a whole and develop it was a bonkers decision !
Heraf clearly went for the straight talking approach with the players and with his lack of knowledge around the culture there was no way back for him. This approach im sure was acceptable for him in Europe in a professional environment which NZ is not but he needed a more tactful approach here and to try implement change over time. I believe he meant no harm with his honest view and approach but it was definitely not the right way to do things and it has clearly backfired on him. Again why did Andy Martin not advise him better ? Again because Andy Martin does not understand the culture !
I could get into the NZ football culture but i would need to write a book : )
