David Warner believes the influence of Brendon McCullum is so great that New Zealand cricket will struggle to overcome the retirement of their highly-regarded captain.
Two of the game's most powerful hitters might have clashed heads in recent times - McCullum labelling the Australian opener "petulant" and Warner responding by telling the Black Caps' "Mr Nice Guy" to mind his own business - but the respect is strong.
Warner says despite their very public difference of opinion following a controversial newspaper column McCullum wrote in the aftermath to last year's Ashes, there are few cricketers in the world he would rather share a beer with.
McCullum will today play his 100th consecutive Test match, an extraordinary achievement.
New Zealand can use McCullum's looming retirement as motivation to topple Australia in what would be a historic achievement, but once this series is over, Warner says the Black Caps will find it difficult to fill the giant void he will leave - so immense is the 34-year-old's influence.
