"It's very difficult as names have been bandied about and football is precarious. You could be talking about one of the potentially exciting young managers - is he going to be here in two years?
"I think top managers will always be in demand - Guardiola, Mourinho, David Moyes, there are a lot of successful managers out there and I don't know what their plans are.
"Who knows where they will be in two or three years."
As Goal.com exclusively revealed in September, Sir Alex has turned his attentions to identifying a suitable successor and has earmarked Guardiola and Mourinho as two able candidates.
However, with United cementing their seven-point lead over champions Manchester City with a resounding 4-0 win at Wigan on New Year's Day, Ferguson is clearly still enjoying the rigours of management.
"It was a perfect start to 2013. It has given us a seven-point lead with 17 games left," he added.
