Pristine surfaces, the all-white dress code, strawberries and, most importantly, the world's best tennis players all striving for one of sport's most prestigious prizes. And it is all about to start again. Here are the key things you need to know. The gates open at Wimbledon on Monday, but the fun started a week ago. Qualifying began on Monday, 26 June as lower-ranked players not automatically in the draw competed for the 16 remaining men's places and 12 women's spots. Britain's Alex Ward, ranked world number 855, took one of them, but the likes of Marcus Willis, Liam Broady and Katy Dunne did not make it. The seedings, given to the top 32 players in each singles draw, were announced on Wednesday. Things really started getting moving on Friday, when the draw was made. Play begins on the outside courts at 11:30 BST on Monday, before Britain's Andy Murray, the reigning men's champion, has the honour of opening on Centre Court at 13:00 BST. Murray, Wimbledon champion in 2013 and 2016, has struggled with a hip injury in the lead-up to his title defence. The world number one was forced him to pull out of two warm-up matches at the Hurlingham Club, but practised at the All England Club on Friday and Saturday. And, putting aside his injury concerns, the Scot has been well short of his blistering form 12 months ago.

Murray, 30, won the Queen's title before both Wimbledon triumphs, but this month he suffered a surprise first-round defeat by Australian world number 90 Jordan Thompson at the Aegon Championships. "There is no guarantee that I won't do well at Wimbledon, but it certainly would have helped to have had more matches," said Murray before his injury troubles. Seven-time champion Roger Federer, fresh from winning his fourth title of the year at the Halle Open, is still seen by many as the man to beat. The 35-year-old Swiss won the Australian Open in January - a record 18th Grand Slam title. Another success at Wimbledon will put him clear of the men's record of seven singles titles he shares with Pete Sampras, and move him to within one of Martina Navratilova's all-time record of nine. Federer's long-time rival Rafael Nadal is also among the Wimbledon favourites after winning his 10th French Open crown at Roland Garros. Nadal, 31, has overcome his own injury problems to climb back up to second in the world rankings. Novak Djokovic held all four Grand Slam titles going into last year's Championships. Now he holds none. The 30-year-old Serb, who rediscovered some form by winning the Eastbourne title, has dropped to fourth in the world rankings after a troubled year in which he has split with his coaching
