Michael Vaughan, the former England captain, wanted the Durham all-rounder to be drafted in after the 5-0 Ashes whitewash.
Vaughan even suggested Collingwood could lift morale in time for their forthcoming one-day series. However, Collingwood, who captained the English to WorldT20 victory in 2010, insists he will not be quitting his role as Scotland's joint interim coach. The Scots launch their bid to qualify for the World Cup next week and Collingwood said: "I'm enjoying my role with Scotland. I've got a month with them in New Zealand where we're trying to qualify for the World Cup. Hopefully I can help make them better cricketers and they can learn a lot from me. I'd welcome a call from England when the time is right and it would be very hard to turn them down but I'm still at Durham and have another year on my contract."
Scotland open their campaign against Hong Kong in Queenstown next Monday. They must finish in the top two of the 10-team event to reach next year's World Cup in Australia and New Zealand.
