Which of these achievements at Roland Garros would be the most significant?
Novak Djokovic wins a first French Open title to become the first man since Rod Laver to hold all four slams at the same time.
Arguments for: In the strongest era of all time, he would achieve something that has been beyond Roger Federer and Rafael Nadal. Victory would also mean that Djokovic would complete the career grand slam. Some, including Boris Becker, have argued that a Nole Slam would put Djokovic on the same level as Federer and Nadal.
Quibbles against: It would not be a calendar grand slam, unlike Laver’s two (in 1962 and 1969), and Don Budge’s (1938).
How it would be celebrated: Champagne, karaoke, street parties in Belgrade, high fives in Tokyo.
Rafael Nadal wins a seventh French open title to supersede Bjorn Borg’s six titles.
Arguments for: He would officially become the most successful clay-court player of the modern age.
Quibbles against: None (though some may speculate how many more French Open titles Borg would have won if he had not taken premature retirement).
How it would be celebrated: Dinner at a restaurant overlooking the Eiffel Tower; thinking of Majorca’s beaches.
Roger Federer wins a second French Open title for a 17th grand slam title which extends his record as the most successful male tennis player in history.
Arguments for: Winning his first slam title for more than two years – since the 2010 Australian Open – would show that there is still plenty of life left in Federer. It would also give Federer great momentum before heading over the Channel for Wimbledon and the Olympics, and raise the possibility of the Swiss regaining the No 1 ranking.
Quibbles against: None.
How it would be celebrated: Not by wearing a jacket embroidered with a golden ’17’ on the back.
Andy Murray wins a first French Open title to become Britain’s first male grand slam singles champion since Fred Perry in 1936.
Arguments for: The waiting would come to an end.
Quibbles against: Outside Great Britain, would a victory for Murray have as much impact as a win for one of the other three?
How it would be celebrated: A teetotal evening, an early Eurostar and a helicopter ride to Dunblane. No need to put up any bunting in Britain – it’s up already for the Queen’s Diamond Jubilee.
