£15m isn’t a penny pinch though is it. It buys you an Akanji for example! Successful business’ don't stay at the top by wasting money for the sake of it or because they can.
This argument is exactly why the right people are running our club, look at Barça, they have had your attitude for years and now find they can’t buy who they’d like as they can’t register them. They are also now facing questions from UEFA, something we’d like to avoid.
£1-2m I get, £5m I’d see an argument for, but again that’s not how good business’ run and regardless of how we as fans feel, Manchester City Football Club is a business foremost.
