How Pietersen could impact England's Ashes batters

Kevin Pietersen's coaching job with England looks set to remain white-ball-only for now - but he could still have an impact on the team's Ashes batters, says Rob Key. Pietersen began a specialist mentor role with Brendon McCullum's limited-overs outfit during the T20 and ODI series wins over Sri Lanka in September, with that running until the end of the next 50-over World Cup in Africa at the end of 2027.
