You seem to not understand the what I said when they all had their own sources, which was that it was papers publishing their own stories, which their journalists will have sourced, or if they are rehashing the article and crediting Sky's, which they frequently do when someone has an exclusive, but here they are not.
Now, you're demanding I supply the BBC's sources, and patting yourselves on the back when I can't, all the while pretending everyone with a journalism degree is taught a module on how to drag Man City's nam through the mud and that they club would never do anything like this. Apart from the time when we did do this with a kid earlier in the year and got banned, but that was probably a conspiracy too.
