Novak Djokovic and Carlos Alcaraz are locked in a tight battle for ATP Year-End No. 1 presented by Pepperstone honours, but that did not stop them from practising together on Sunday.

The top two seeds at the Rolex Paris Masters enjoyed a training session before the start of the final ATP Masters 1000 event of the season. The top-seeded Djokovic, a six-time champion at Bercy, will open his tournament against doubles partner Miomir Kecmanovic or Argentine Tomas Martin Etcheverry.

Alcaraz, the second seed, will try to make a good start against home favourite Alexandre Muller or Roman Safiullin. He is pursuing his seventh trophy of the season.

Djokovic currently owns a 500-point lead over Alcaraz in the Pepperstone ATP Live Race To Turin, which serves as a barometer for the year-end World No. 1 battle. But with 1,000 points up for grabs in Paris and the Nitto ATP Finals still to come, the battle is very much alive.

One year ago, Alcaraz became the youngest year-end World No. 1 in Pepperstone ATP Rankings history. Djokovic is trying to earn the honour for a record-extending eighth time.
