Yes and I can prove that.
Remember when Aguero got a retrospective ban for a supposed elbow on Winston Reid? The ref was Andre Marriner and his initial report said he saw it and didn't see it was a red card offence. He was asked to change that to say he hadn't seen it (so Aguero could be retrospectively charged) but initially refused.
He was then promised the League Cup final if he changed his report, so he did and he got the gig. I told people on here about that well before his appointment was announced. This came via a senior source at the club.
Then there was the Adebayor celebration after his goal against Arsenal. Clattenburg booked him for it, which he was entitled to do as goading the opposition fans is an offence. However the Head of the FA was an Arsenal fan called Ian Watmore, and on live radio on the Sunday morning, he said Adebayor would face a charge for his actions.
The problem was he'd already been booked for it, which would normally preclude a further charge so they had to find a way out. The involved getting Clattenburg to change his report to say he'd booked Adebayor for time wasting. So he could then be charged and got a suspended ban. I was at a meeting with club officials at that time and they were absolutely furious about it.
If that's not corruption then what is it?
