Swales is a type of guy who I have met a few times in my life. Runs some tin-pot business and thinks that on the strength of that they are some sort of managerial genius who can run anything better than the people who actually do and know the job. A pitiable lack of self-knowledge.
A true blue who loved Manchester City? Possibly. But if so, so were about 40,000 others, of whom about 0.1% (not including me, by the way) would be fit to run the Club.
His worst decision? Where do you start? It all comes down though to his unwillingness to put a penny of his own money into the Club, while leeching a fat salary (for the time) out of it. That is why we were left on the starting blocks.
