Will Novak Djokovic put himself three-quarters of the way to achieving the calendar-year Grand Slam? 

Djokovic's love for raw, vegan food extends to the Centre Court grass: on the three previous occasions he won Wimbledon, he snacked on the lawn. And if he ends up eating the turf again in a fortnight's time, it will signify that he is 'just' the US Open away from achieving the near-mythical Grand Slam. Already the Serb has accomplished what might be called 'The Nole Slam', with his Roland Garros triumph making him the first man since Rod Laver to hold all four majors simultaneously. 

But for all tennis traditionalists, and others besides, the ultimate in tennis is to sweep through Melbourne, Paris, London and New York in the same season, which hasn't been done in men's tennis since Laver in 1969. 

This is the first time since 1992, when Jim Courier was the alpha male of the tennis jungle, that someone in the men's game has arrived at the All England Club after winning the Australian Open and Roland Garros titles earlier in the year. And how did the American fare on the grass? He ventured no further than the third round. You suspect Djokovic will run a little deeper into the draw.

Will Serena Williams equal Steffi Graf's Open era record of 22 majors?

There are far worse places to be 'stuck', but for almost a year Williams hasn't moved off 21 majors.

That last Grand Slam victory came here at Wimbledon, as she lost in the semi-finals of last season's US Open and finished as the runner-up in Melbourne and Paris this season.

Should Williams lift the Venus Rosewater Dish once again, she would draw level with Graf on two lists - as well as equalling her for the most major singles titles since tennis turned professional in 1968, she would also achieve parity with the German on seven Wimbledon triumphs apiece. 

That would mean joint second place in the Wimbledon list - Martina Navratilova would still be out there on her own with nine.

Will Garbine Muguruza score her second Grand Slam of the European summer?

Last summer's adventures on the Wimbledon lawns, when she made her first Grand Slam final, will surely have persuaded the Spaniard that grass is good for more than just grazing cattle.

Any grass-court anxiety she might have felt would have since dissipated, so she knows she can play on this surface.

She's also aware - as she demonstrated with her victory over Williams in the Roland Garros final, to win her first Grand Slam - that she has the power and poise to win the sport's most glittering prizes.

Will Muguruza make the successful leap across the Channel, bringing that Parisian form with her? 

Will Roger Federer score his first Grand Slam title for four years?

Clearly, this has been a trying season so far for the 34-year-old Swiss, what with injuring himself while giving his children a bath, as well as dealing with a virus and a back injury.

His absence from the French Open, because of his back, broke a run of consecutive Grand Slam appearances that began last century.

But where better for Federer to revive himself than on the lawns of London, where he has already won seven titles? For Federer's last major triumph, you must rewind to the summer of 2012 when he came from a set down to defeat Andy Murray. 

But he has reached the final in London for the past two years, on both occasions losing to Djokovic. 

If Federer can touch the heights - as he did against Murray in last summer's semi-finals, with a serving performance which bordered on perfection - then anything is possible.

Will Andy Murray's decision to re-hire Ivan Lendl bring him a second Wimbledon title?

Three long years have passed since a British man last won Wimbledon. Clearly, that's a mere blip in time when set against the 77 years between Fred Perry's 1936 triumph and Murray's golden summer of 2013.

But, for someone with Murray's talent and ambition, it won't sit easily that he hasn't won a Grand Slam title since that day he defeated Djokovic in straight sets. That's also the last occasion he beat Djokovic at a major. 

Murray's decision to reform his partnership with Lendl, the man who coached him to the 2013 title, demonstrated that the Briton's All England Club's ambitions weren't sated with one title.

He wants another, and Lendl might just prove to be the difference, while also adding a layer of intrigue to the tournament, with the possible coaching confrontations with John McEnroe (Milos Raonic) and Boris Becker (Djokovic).

Will Madison Keys or Belinda Bencic reach a first major final?

Keys' aptitude for the sport's original surface was clear when she reached the quarter-finals of last summer's Championships.

There are times on grass when power negates everything - that's certainly true when Keys is landing her ferocious serve; or smacking her forehand.

So far, the 21-year-old American's best career result at the Grand Slams was making the last four of last year's hard-court Australian Open.

But could this be the fortnight when Keys, now a top-10 player, makes the second Saturday of a major for the first time?

Or perhaps it will be Bencic, a 19-year-old Swiss who uses plenty of spins and angles on court, in the style of her fellow countrywoman Martina Hingis?

Like Keys, Bencic is now in the top 10.Can she eclipse her previous best at the majors, which was advancing to the quarter-finals of the 2014 US Open?
