Chants of ‘Nole, Nole, Nole!’ rang around the stands as Djokovic and Zverev clattered the ball with such clean and crisp precision, dialled in from the very first strikes.

Earlier women’s reigning champion Coco Gauff returned to Roland-Garros to get ready for her title defence.

The American noticed a photo of herself lifting Coupe Suzanne-Lenglen on the walls backstage and posted it to her Instagram account with a simple message ‘back.’

Gauff did her training over on the greenhouse-surrounded Court Simonne-Mathieu, fine-tuning her game following Saturday’s thrilling Rome final, when she lost narrowly 6-4, 6-7(3), 6-2 to to Ukraine’s Elina Svitolina.
