Maybe they prefer to wait until he's retired and he can actually be there to see his children. Apparently it's already difficult enough to have a steady relationship when you're always gone, so having children must be frustrating. Especially when you play a lot like David. Federer has children but he does not play much
Yeah, that's obviously the case, I can remember Davydenko saying a similar thing. So basically we should root for Marta not getting pregnant at the moment, because that will be the end of David's career
I like their way of thinking better, although I can see the argument for having children in your twenties instead of after retiring in your early to mid thirties. A lot of players go that way, from the top of my head Wawrinka, Simon, Haas, Hewitt, Llodra, Baghdatis and Youzhny are all fathers.
