Brendon McCullum is set to bring a no-nonsense coaching philosophy to his new role as England Test coach, with the 40-year-old infamously instituting a "no d***head" policy during his time as New Zealand captain.

Ryder, described by McCullum as New Zealand's "most talented player" outside of Kane Williamson, saw his career blighted by off-field issues and he only played 13 internationals after McCullum became captain.
"It took us a long time to get where we wanted to be and we lost some people along the way," McCullum told All Out Cricket in 2016. "And the 'no d***head policy' is pretty important too.
