This is only what the Premier League has been doing to football in Belgium, Norway, Holland and even France since its inception: buying up its talent with money the domestic clubs couldn't possibly rival. There's an element of biter bit in the griping.
But oddly this is likely going to benefit the Premier League still further, since this is much the best known foreign league in China and the Chinese are about brand-shopping.
Oscar who hasn't played for Chelsea for 3 months goes for £52m, Chelsea makes 4 buys in Europe at £13m apiece. Now the Chinese wouldn't have bought these 4, and not just because they couldn't scout them. They want to pay the premier league premium because "bought from Chelsea“ means something to a largely uninformed Chinese public while "bought from Standard Liege" does not.
