Lacoste said Monday it wants to review events that sparked a nearly two-week legal battle and prevented the unvaccinated Serb from defending his Australian Open title. Australia requires international visitors to be vaccinated against Covid-19 unless they have a medical dispensation.

"As soon as possible, we will be in contact with Novak Djokovic to review the events that have accompanied his presence in Australia," the French clothing brand said in a statement.

"We all wish an excellent tournament and thank the organizers for all their efforts to ensure that the tournament is held under good conditions for players, staff and spectators," it reads.

Djokovic's sponsors have said very little since his visa was only revoked shortly after his arrival in Australia on 5 January. It is unclear when Djokovic will go to court again. He gets the chance to beat the men's grand slam title record at the French Open in May, but events in Australia have raised questions about how unvaccinated players will compete on the season tour.

French carmaker Peugeot, another Djokovic sponsor now owned by Stellantis, declined to comment Monday. The Swiss watchmaker Hublot and Japanese sportswear giant Asics (ASCCF) did not respond immediately to requests for comment.

Djokovic has $ 30 million a year approval agreements, according to Forbes, and was the world's 46th highest paid athlete in 2021.

World No. 1 was scheduled to play Monday night in Melbourne, where he had hoped to win a record-breaking 21st grand slam title for men.

Instead, he left Australia on an Emirates flight en route to Dubai after losing his legal challenge to a decision to revoke his visa for the second time. He arrived back in the Serbian capital Belgrade later Monday.

In a statement, Djokovic said he was "extremely disappointed" with the decision.

"I'm uncomfortable that the focus in recent weeks has been on me and I hope we can all now focus on the game and the tournament I love," the statement added.

Lacoste was founded in 1933 by the 7-time grand slam winner, René Lacoste, and entrepreneur André Gillier. The brand became famous for its light cotton polo shirts with the logo of a crocodile - a nickname that Lacoste got during his playing days.
