, however I agree with some posters that Dubai should be on it as well since Roger has done well there, partly because it's one of his favourite events.
I'm only moderately optimistic about Roger winning MC, and I seriously doubt he'll take RG. He should have a decent shot at Rome and Paris, and more than that on Basel.
The Olympics is of course hard to guess since it is rarely played. I think his chances are slim. Anyway I don't rate that achievement very highly because of its limited historical significance for tennis.
