If it was this, then it is out of date...
That is based on the claim Gao Jisheng was worth £3b, not Dragan Solak.
Solak's wealth has been reported in some media to be closer to £1b.
Plus in any case, what the owner is worth doesn't matter as much as how much they are willing to spend. Solak investing some of a £1b fortune is better than Gao not investing any of the £3b (if he even had that much!).
