Joe Root has expressed his full support for the management team of Brendon McCullum and Rob Key, crediting them for the England cricket team's improvement. This comes amid scrutiny following England's Ashes series loss to Australia. While some critics have called for McCullum's dismissal, Root highlighted the individual and team progress under the current leadership. England's recent four-wicket win in the fourth Test at the MCG, their first there in over a decade, offers a slight reprieve despite losing the series.
