(Reuters) -England coach Brendon McCullum has urged fans to keep faith despite a disastrous start to their Ashes campaign, with hosts Australia clinching an eight-wicket win in Perth on the second day of the first test.

"Bazball", an attacking batting strategy backed by McCullum and captain Ben Stokes, has faced stinging criticism after England batters fared poorly in the shortest Ashes test by overs bowled to deliver a result since 1888.
