World ranking: 7
Justine Henin-Hardenne sent out a warning to her Wimbledon title rivals by claiming her second French Open crown just three months after returning to the sport.
The Belgian has had to learn to cope with a draining viral condition that virtually wiped out her 2004 season.
A right knee injury before the Australian Open in January made matters worse and Henin-Hardenne withdrew from the tour until March.
Her comeback in Miami was satisfactory - she was knocked out in the quarter-finals by Wimbledon champion Maria Sharapova.
But it was in the clay-court season that Henin-Hardenne found her rhythm, finishing it undefeated in 24 matches and with a fifth Grand Slam title under her belt.
The 23-year-old's trademark athleticism on court and powerful groundstrokes seemed undimmed by her time away from the circuit.
And her energy levels should be soaring before Wimbledon as she opted out of the traditional warm-up tournaments, preferring to rest.
The Belgian admits her condition has made her more determined on court and more careful about her health off it.
Henin-Hardenne has an excellent record at Wimbledon, reaching the last four in 2002 and 2003 and finishing as runner-up to Venus Williams in 2001.
If she arrives in peak shape at the All England Club she will be strongly fancied to go one better.
