Rumor has it that Justine Henin, winner of 7 Grand Slam titles, could be considering a comeback. Henin, who shocked the world and retired in May of 2008, has reportedly begun training for exhibitions. Kim Clijsters, a longtime rival of Henin, just recently returned to the WTA Tour and took the same route, starting in exhibitions and working her way up. Belgian news source Vers L'Avenir has apparently recieved confirmation from the former world number one's entourage about the training. I'm sure Henin knows that she could blow each and every woman on the tour out of the water.
