Roger Federer's loss this week will be a painful one, unless Rafael Nadal loses in the semifinal or final. The world no. 1 ranking is on the line because both players are less than 1,800 points away from each other.
If Nadal wins the title, he will have enough points to go back to number one because Federer's points will be falling off, almost 1700 points to be exact. The Spaniard will be looking to win the title and probably does not think about where he goes in the ranking.
