Kevin Pietersen has backed incoming England and Wales Cricket Board chairman Colin Graves to make the changes needed to revitalise the national team. Graves will take up his new post in May and high on his list of priorities will be to reinvigorate England's one-day side, who were knocked out of the World Cup in the group stages after an embarrassing loss to Bangladesh on Monday. The defeat gave ammunition to those who believe it was a mistake to axe Pietersen from the international set-up 14 months ago, while Graves appeared to leave the door open for the star batsman earlier this month when he suggested he would have a better chance of an England return if he played county cricket in this country.
