The former Austraila cricket coach John Buchanan has warned South Africa's Mickey Arthur might have to overcome some cultural issues as the first non-Australian cricket coach.
And Buchanan - now New Zealand's director of cricket - knows all about the pitfalls of coaching outside his native country.
He might have had the Midas touch during his eight-year stint as Australian coach, but the Knight Riders sacked him two years after they finished last in the Indian Premier League.
He says it takes time to be understood and merge into a new system and there are cultural issues, even down to your language and your body language.
Buchanan says his work with the New Zealand team will not start to come to fruition for at least two years.
He says he would have found it very hard coaching against an Australian side but his role is very different - it is about shaping New Zealand cricket.
