Carragher simply hasn't read the details. I'm not sure he's read the Der Spiegel report. I'm not convinced, deep down, he understand the accusations. I don't think he read and/or understood the CAS report, or what the time barred really meant.
Obviously - obviously - City have taken advantage of their links with commercial partners attached to the club. Like United, like Leicester, like Bayern, like Stoke, like Juventus like [insert a dozen other football clubs]. But obviously those links are mutually beneficial for those sponsors. But City are the most successful club in England over the last decade, are on TV more regularly than anyone, and have exploited emerging commercial markets in creative ways as you would expect directors who are at the cutting edge of European football. Txiki Begiristain proposed all this at Barcelona, and the dinosaurs there saw him off for it, so he took the template and brought it to rainy Manchester cos he'd figured out business plans and football plans that the rest of European football are now trying to copy. Carragher still seems to think that Real Madrid should be top of the table because they sell more shirts and have more Facebook followers. Well, if Spurs made £442.8m, having not won a trophy in a decade while in the UEFA conference league, why shouldn't City have made £619.1m winning the league and getting to the semi finals of the CL? That sounds about right to me.
