Wimbledon: Nadal, Wawrinka, Serena, Sharapova, Djokovic Get Set
Nadal is down to number 10 in the seeding, but says he is feeling confident despite a string of injuries that have plagued his game over the last 12 months.
For Wawrinka, he is one of the few who has been able to challenge the dominance of the big four claiming two grand slams in the last 18 months, in Australia and most recently in France.
He is, however, playing down his achievements.
Serena, Sharapova Talk Chances
Meanwhile, Serena Williams heads into the 40th Wimbledon since Arthur Ashe became the first black man to win a grand slam, knowing that she can mark his achievement with another victory at SW19.
Williams has won five championships at Wimbledon and she attributed her success to his huge influence.
One of her main rivals for the title will be Maria Sharapova, who famously beat the American in the final as a 17-year-old in 2004.
The Russian believes Serena is the player to beat at the tournament.
Djokovic Expects Tricky Tie Against Kohlschreiber
Wimbledon Champion, Novak Djokovic, says facing Philip Kohlschreiber in the opening round will be a tricky test.
The world number one is bidding for a third Wimbledon title and will start play on centre court on Monday.
He goes into the match without any competitive warm up game.
Djokovic reached the final of the French Open three weeks ago, but suffered a shock loss against Stanislas Wawrinka and he admitted the defeat was hard to swallow.
