The number in brackets denotes seeding for the tournament.

Novak Djokovic (1)

The Serb must feel a little lost at the moment. His form, particularly at Masters events, has been excellent with victories at Indian Wells, Miami and Rome this year. Grand slam finals have been hurting him though, with only two wins from his last seven outings. He should go deep here, especially with the added guidance of former champion Boris Becker.

Rafael Nadal (2)

While Djokovic has slightly gone astray mentally, Nadal’s problems seem purely of the physical kind. The Spaniard’s style has always taxed his body, chiefly the knees, but he now has a back problem to contend with. It ruined his Australian Open final and clearly affected him at the French Open.
He has exited Wimbledon early on the last two occasions, and I think a similar performance could follow. The monster serves of Ivo Karlovic or Milos Raonic may cut his London trip short.

Andy Murray (3)

It’s been a peculiar season for the defending champion. Coaching changes, fitness issues and early losses have been the order of the day. His fortunes seem to have turned though. An impressive semi-final run at Roland Garros was followed by the appointment of former Wimbledon champion Amélie Mauresmo as coach. With his nimble footwork and superior hand skills, the Scot was born for this surface, and I expect him to win or go extremely close.

Roger Federer (4)

Sadly, it’s getting to the ‘last chance saloon’ stage for the magnificent Swiss. The greatest grass court player we’ve seen just can’t seem to get over the line in five set matches any more. He was brushed aside by Nadal in Melbourne and lost a titanic match to Ernests Gulbis at the French. That being said, he won the grass tune-up event at Halle, and he’s still formidable on this surface. However, it hurts me to say that I don’t think he can win these events anymore.

Stan Wawrinka (5)

The Australian Open champion, who dispatched Djokovic and Nadal on his way to victory there, is the unpredictable sort. After playing possibly the greatest tennis I’ve watched to claim his maiden slam, Wawrinka’s form has been erratic since. If he is tuned in, the engraver may just need a new template come Sunday fortnight. But we haven’t seen him like that since the start of the year.

Milos Raonic (8)

The Canadian has had a solid year in 2014 with no tournament wins but a host of runs to the final eight. He has always commanded a gigantic serve, but his game style has been refined by coach Ivan Ljubicic. He could and should cause trouble to the field.

Grigor Dimitrov (11)

The Bulgarian has had an excellent season so far with victories at Acapulco, Bucharest, and last week on the grass at Queen’s. He has an all-court game and belief from wins over the likes of Murray, Wawrinka and Berdych. I expect him to make an impact.

Ernests Gulbis (12)

The lazy, outspoken underachiever has become a focused winner and a danger to everyone in the draw. The Latvian clearly likes France as he claimed titles at Marseilles and Nice earlier this year, and reached the semis at Roland Garros, dispatching Federer and Berdych along the way. On form, Gulbis can beat anyone.

I believe them to be the main contenders but also keep an eye on Queen’s finalist Feliciano Lopez, who is wonderful on grass, and Dominic Thiem who should have a big say in the game going forward.
