Take your pick: Who will win the 2009 Barclays ATP World Tour Finals?

Who do you think will win this year’s Barclays ATP World Tour Finals? The undefeated champion of this event will earn 1,500 ranking points. Could this be Rafael Nadal‘s chance to grab the top spot from Roger Federer? Or would there be someone other than these two top-ranked players who will emerge as the victor. Defending champion Novak Djokovic will surely make things interesting and British number one Andy Murray will certainly exert more effort since this event will take place in his home country. Make that vote on the poll posted on the right column of this site.
