Players who took part in the invitational event in the US wore masks, kept their distance from each other and played matches behind closed doors.

Bouchard, who filmed herself struggling to pop open a bottle of champagne on court following her final match, was pictured touching rackets with other players rather than shaking hands or embracing her fellow competitors.

"Our team won but the fact we could play tennis in a healthy and safe environment is a win in itself," she said.

"We played better than we celebrated, I promise. Can someone teach me how to open a champagne bottle, please?"

The scenes in South Carolina were in stark contrast to the tactile cameraderie at Novak Djokovic's recent Adria Tour in Serbia and Croatia, which resulted in the men's world number one, three other players and Djokovic's coach, former Grand Slam winner Goran Ivanisevic, testing Covid-19 positive.

Former French Open semi-finalist Andrea Petkovic replied: “So far, from what I can gather, female tennis players have conducted themselves in an admirable manner in these trying times of crisis. Am I right?"
