That doesn't really make any sense. I've lived in Asia for almost 15 years and love it here. I wouldn't want to live back in England or Europe. Why do you assume he isn't attracted by Asian culture?
If he is interested in Asian culture, the Chinese league would be a good fit and he could earn loads of money at the same time.
Saying that, I do think money is his main motivation. He could easily go to a more competitive league and then retire in Asia.
You answer this yourself by also thinking Money is his main motivation. 31 years old wants to play football but the only option he has had any interest in is to the only league he would have had a pay rise in. The culture would be something to appreciate and likely enjoy but you think playing in London & Madrid suddenly means Munich? Milan? Would not be attractive to him? Needless to say that is if they even held an interest (Bayern did?).
So you think it’s inconceivable that a man who has spent his life working in two European capitals and has through those jobs plied his trade in countless other great European cities would be interested, while he’s young enough to still take full advantage of it, in experiencing the totally different culture and way of life of an oriental city?
Would you say the same if he was, I don’t know, an ISDA negotiator within a major bank?
To answer that you would have to look at the bigger picture right? We are comparing a top top footballer playing in one of the top 5 leagues in the world, to play in one thats like around 20th or worse. There fore he would be getting a pay rise while not having to really put in the same kind of effort effectively.
Would this negotiator be going to a worse bank to earn more money in the knowledge he would not really need to work as hard to earn it? Because in that scenario the culture is a bonus if he wants more money less stress at work. I guess when he leaves Madrid we will find out if the Asian Culture appeals as he will still have that option just not on ridiculous money after the cap.
