Well I think .. My idea is, that the big four always secures, that the decision is always between them.
If Ma Long, Fan Zhendong and Xu Xin see that Zhan Jike is not doing well in the qualifications or trials, they would purposely lose to him to give him needed wins so he can qualify. The real fight will be after it just between players of the big 4.
That is what I think. And I think this already happened.. Just watch the results of the previous trials and you will find some completely weird loses that in the result secured the big 4 fighting for the places (before it was Wang Hao instead of Fan, of course..)
For this World Cup, well I really hope Ma Long will win, he is the real Captain. Fan is the beast, but comparing to Ma Long he is a no brainer. I am not saying he is stupid, just.. compared to Ma Long..
If Ma Long will be recovered from the injury, there is no force stopping him to get this one!
