I'm struggling with your train of thought here...do you honestly think clubs down South would be put off pursuing Allan Campbell, because 'he might not fancy moving'?
It's a short career and I'll guarantee you that unless Celtic or Rangers are interested in a player up here, then 99.9% of the footballing population wouldn't think twice about moving South for the riches that are down there in comparison to here.
If Campbell ends up at Hibs or Aberdeen, it's purely because nobody else showed an interest.
