Still in the hunt for London
This year is no different, with any one of seven or eight players potentially still in the hunt for a place in the London field.
Nadal, Djokovic, Daniil Medvedev, Federer, Dominic Thiem and Stefanos Tsitsipas have already secured their ATP Finals spots, while Sascha Zverev and Matteo Berretini occupy places seven and eight.
Good performances in Paris would seal the deal but Roberto Bautista Agut, David Goffin, Fabio Fognini and Gael Monfils are all still in with a chance of making London, which will make things even more exciting, especially if Monfils can follow in the footsteps of some of his countryman who have found their best form on home soil down the years.
Guy Forget, who went on to be the tournament director, won the title in 1991, when he famously took down Pete Sampras in a five-set thriller for the win of his career.
Sebastien Grosjean took the title in 2001 while Jo-Wilfried Tsonga won it in 2008. And Monfils was agonisingly close to taking the crown in 2009, when he was edged out in a final-set tiebreak by Djokovic, and also finished runner-up in 2010.
Monfils will carry most of the hopes of the home crowd who will join him inside the cavernous centre court, which can seat more than 14,000 fans.
Having enjoyed another good year, including his eighth career title, in Rotterdam, Monfils knows that he needs one big push if he is to make it to London, a push that may depend on how his fitness holds up.
