Stokes on Monday announced his sudden retirement from ODI cricket, saying that the rigours of playing all three formats of the game were "unsustainable" for him and he was not able to give his 100 percent to the team in the 50-over format.
Giving an insight into his new coach's coaching style and philosophy ahead of the first Test against New Zealand at the Lord's later on Thursday, said McCullum has explained to them the way he coaches.
Stokes' 16 maximums set a Championship record, surpassing those of Australia's Andrew Symonds (1995) and England's Graham Napier (2011) for Gloucestershire and Essex, respectively.
The two ageing warhorses were strangely left out of England's three-Test tour of the Caribbean earlier this year, with selectors instead opting to give more opportunities to the next generation of seam bowlers.
While England has the "right personnel in charge," Pietersen believes the entire cricket structure needs a "shake-up" to get the team out of its "doom-and-gloom" situation.
He succeeds right-handed batter Joe Root, who resigned from the role in April this year, in becoming the 81st captain of the England men's Test team.
A report in iNews said that England men's cricket's new managing director, Rob Key had travelled to Durham for a "face-to-face" meeting with Stokes to "discuss the role", and that the 30-year-old all-rounder could be officially unveiled as England's new Test skipper "in the next 48 hours".
