Seriously guys, what is SO wrong with some of you? It's a very simple statement so don't make too much out of it. I know fully well that a lot of Murray fans are very keen on the ranking, but I've always maintained that Murray himself is not very keen. He just wants to win more Slams and if the No. 1 position comes with it then that's dandy too, but he's not going to fight for it. It's two very different elements and Murray does realize that achieving both is not a very realistic goal at this point. But more importantly, if he continues to win Majors and Masters (and he does like some of those), the ranking will take care of itself. Sampras, for example, wanted to be No. 1 for a number of years and he planned all his schedule that way and he did achieve that. To Murray, it's simply not a priority.
As I see it, his next goal should be to defend USO and win WTF this year, something he deeply cares about and he's the 2nd best on that surface (by that I mean indoor) after Federer despite not winning at least one time, but his time is on the rise.
It won't be too bad if he takes a few more titles in between like Montreal, Shanghai, Tokyo etc. All the top four will be gunning for all these as well no doubt.
