he might but fast from yesterdays games are that Murray played 3 exciting sets with Raonic where both players have match point and Murray at the end won he played more then 3 hours match and that may be his backfire, on the other hand Djokovic quite easy got his match and seem to be determent to take again first spot at this season end
expect great match to see with 3 sets that would be quite well to see and in the end may the best player win and take first place for this season
both players have played good Djokovic first part and Murray second, good is that they will play each other to determine the best tennis player for this year
