'She pushed me so much' - Justine Henin 'grateful' for Serena Williams rivalry after American announces retirement
Justine Henin says facing Serena Williams was the “biggest challenge” of her career and that their matches pushed her to be a “better player”. Henin and Williams were involved in a number of high-profile clashes over the years, including the French Open and Wimbledon semi-finals in 2003 and the Australian Open final in 2010. They also met in three of four Grand Slam quarter-finals in 2007, all of which Henin won.
