As far as I know, they were only threats. I could be wrong, but I don't think he has ever gone as far as to formally say he wants to go.
On a serious note I'd imagine there is only man city or PSG who could match what he is on at barca hope he comes england though.
United and Chelsea probably could, though Abramovic already looks likely to shell out at least a quarter of a billion quid this summer.
Just watched a clip from the Transfer Centre on Sky. He's paid a million a week. £9m a year in image rights. £13 million a year in bonuses. £25 million in loyalty fees and other bonuses. He can choose to leave for free at the end of each season, but Barca could argue that the period for that is June/July and not August.
I was just trying to work out what he would get annually on a million a week, then it came to me: 52 million. Long day! Incredible amount of money though. 99 million a year on those figures!
