Djokovic is a former Wimbledon champion and renowned as one of the toughest-ever competitors. He is associated with marathon matches and normally wins them, so it remains to be seen how wounded he will be by Rafael Nadal's defeat of him at the French Open. On his day he is unplayable and one blemish cannot rule that out.
Nadal will likely start Wimbledon as the fifth seed, which is staggering considering he has just won a 12th grand slam title. His eighth Roland Garros success was all the more impressive considering it came after a lengthy injury absence, with his problematic knees certainly part of the reason behind his surprise loss to Lukas Rosol at SW19 last year.
It has long been said Federer's star is on the wane but the Swiss has always managed to find an answer. His last grand slam title came at Wimbledon a year ago - that was his 17th but second in three years - and can never be ruled out on grass. His dismantling at the hands of Jo-Wilfried Tsonga at the French was one of his worst defeats, though, and his level of response remains to be seen.
British number one Murray can play in his home grand slam free of the burden of trying to win his first major tournament having won at Flushing Meadows last year. He tearfully lost in the Wimbledon final in 2012, so at least knows how to get there, but a lack of big-match practice owing to the back problem which ruled him out of the French is a worry.
While one of the most likeable players on tour, Tsonga is also one of the most puzzling. He can be brilliant - as he has memorably been twice against Federer in the past - or he can be absent, as he was in his French semi against David Ferrer. He is a laid-back character, though, and disappointment on home turf should be easy to shrug off.
Ferrer may have an 'always the bridesmaid' feeling about him after losing to Nadal in the French final - his first grand slam showpiece. He is as competent as they come on any surface, though, and he is one of the most consistent performers on the tour. He may never get the better of Nadal on clay and grass is not his favourite court, but he has the game to go deep.
Another Spaniard, Almagro has quietly edged his way into the top 10 over recent seasons and although he enjoys the red clay, has proven his worth on other surfaces as his quarter-final appearance in Australia showed. Staying power seems to be his problem - he served for the match in Melbourne but lost and also squandered a two-set lead in Paris.
The Frenchman has made a quiet climb back into the top-10 after a spell lower down the rankings when off-court problems affected his game. It is easy to forget he is only 26 and he was one of the tidiest games on the circuit, meaning he is a threat to most. Often Gasquet has made the middle rounds and faded but, with a favourable draw, may hang around long enough to make an impression.
If given the nickname 'Baby Fed' you have to have something about your game and Dimitrov has, clearly, with a victory over Djokovic to his name this year. Performances in the slams have to come, though, and at 22, this could be the time for him to start making a big impression.
Juan Martin del Potro
Injury and illness continue to blight the Argentinean, who missed out at Roland Garros because of a virus. On the rare occasions he has been fit he has troubled the very best, winning the US Open in 2009, and at 24 he still has plenty of time to win further trophies. An outside chance for this one.
