Endacott arrived in England with the Kiwi tourists at the weekend and became the latest name linked with the job vacated by Tony Currie earlier this month.

"I'll announce it at about six o'clock on Saturday, not to try to keep Frank guessing, but because that's the way I like to do things," he said. "We've got one or two ideas we want to discuss with the players to see that they're happy with it."
