So apparently the definition of being number one must be defined. IMO a number one should be
1/ Consistant the whole year
2/ Winning Grand Slams
The problem this year is that nobody can't pretend to be like that on the Tour. Justine didn't play that much because of illness, Sharapova & Myskina had a lack of consistency.
Momo is the total contrary of them : consistent but not winning big Slams. She's in the same case of Lindsay, but Lindsay is even more consistant than Momo, if u look at their records :
Mauresmo : 53/10 (including Hopman Cup)
Davenport : 58/6
Conclusion : Momo would deserve it IMO only if she wins it. But if Lindsat wins that US Open and still doesn't get the Number 1, the WTA will have to find a solution, because that'd make no sense that a player who didn't win any Slams in her career would become number one, even for a week. The specialists will know why but the general crowd won't understand it.
What's the more important ? To win the final of Montreal against Likhovtseva or to win a hard level fight in the last 16 against Venus Williams ?
