Going to be slightly awkward if and when Bale does rejoin the Madrid squad, given that Zidane basically came out in public and said he didn't want him.
On the general point, I think it's fair to say that different players have different priorities.
China is there, now, as a haven for players who would rather earn tens of millions and have an easy life than challenge themselves in the world's most competitive tournaments. Way I see it, as soon as someone chooses to go there, you can essentially write them off as a player from that day forwards.
Players who actually care about competition and their footballing legacy will steer clear and stick to the Premiership or La Liga.
And then every now and again, you get a player like Joey who doesn't care about money or the competition, and just wants to play for Oxford!
