Nothing to be embarrassed about, not sure where that comment came from?? Djokovic has a chance to overtake as the year-end no. 1 (he has a much better draw than Murray at WTF too).
HOWEVER, if Djokovic did end the year as no. 1, Murray would EASILY reclaim it in the first few months of 2017 as Djokovic has sooooooo much to defend in the first few months whereas Murray has soooo many opportunities to add
to his points tally and not that much to defend. So at worst case scenario Murray ends year as no. 2 and then gets the no. 1 back in early 2017.
Murray was actually aiming for no. 1 in early 2017 anyway as that seemed much more realistic, so the fact he's got there a few months ahead of schedule is just a bonus really!
