Former England skipper Terry Butcher thought the offer to become Scotland assistant manager was a crank call.
But once he was convinced it was his old Ipswich team-mate George Burley on the line, he needed little persuading.
Butcher has agreed to join the new Scotland boss' coaching staff and will take part in the three-day get-together at Loch Lomond, which starts tomorrow.
The former Motherwell manager admitted Burley's initial approach was 'the weirdest call I have ever received'.
Initial excitement about the job was replaced with apprehension about harming Burley's reputation with the Tartan Army, but the ex-Rangers skipper realised if the Scotland boss wanted him, he should join up.
Butcher told the Herald: 'At first I thought it was a radio wind-up.
'I knew it offended people, the thought of an Englishman being part of the set-up, and I thought it would cause George a major problem.
'I wasn't concerned about what people would say about me - I have suffered more criticism than this - but I did not want this to affect George Burley's prospects. I didn't want to present an unnecessary problem for him.
'In the end, the most important thing was he wanted me so I thought, `If it is not a problem for him, it's not a problem for me'.
'The more people I spoke to, the more positive I became. They all said, `Go for it'.'
