Arthur got the top job, on Tuesday, succeeding Tim Nielson. Buchanan, who is New Zealand's [ Images ] director of cricket now after serving eight years as Australia coach, said South African Arthur will have to make a lot many adjustments.
"No matter where you go ... there are cultural issues, no question about that -- even down to your language and your body language," Buchanan, who also served as IPL franchise Kolkata Knight Riders [ Images ] coach, was quoted as saying by the Australian Associated Press.
"Those things take time to be understood and merge into a new system. It is understanding how people tick ... and is that something to do with being in a cricket team or something to do with the country?
"Therefore, you have to be reasonably careful when you make some decisions. I had some less memorable experiences in India [ Images ] with Knight Riders and Middlesex (in England [ Images ] in 1998) for those very reasons," he recalled.
Buchanan and Arthur will be rival dressing rooms when Australia take on New Zealand in a series next month.
