Always had a soft spot for Lee since he started making an impression in the youth teams and his talent was obvious. I think he would have benefited from at least another half season in Scotland. However, when you consider the amount of time he has lost to injury, you can't blame him for taking the opportunity.
Wish him all the best at Leeds and if he settles down South and fulfills his potential, I'll hopefully get to cheer him on in a Scotland jersey.
