Lleyton Hewitt recently said he would "run through walls" to get inside the All England Club for a crack at this year's title.
World ranking: 2
2003: 1st round
The Aussie's determination has never been in doubt and after three years without a Grand Slam win he is optimistic of ending that run at Wimbledon.
Hewitt has done exceptionally well to his establish his counter-punching, baseline style as a major force on grass in recent years.
This season has been interrupted by injury but over the last 12 months he has cemented his position as the leading threat to Roger Federer's reign as world number one.
In fact, before the recent arrival of Rafael Nadal on the scene, Hewitt was looking increasingly like the only leading player determined to take on Federer.
But it has not done him much good so far, with seven consecutive defeats to the Swiss, who remains a huge obstacle to Hewitt regaining the Wimbledon crown.
