Matt Le Tissier praised Novak Djokovic's US Open triumph before sarcastically joking he was surprised by his dominant performance due to his vaccination stance.
Southampton legend Le Tissier has been an outspoken figure in recent years and openly peddled controversial conspiracy theories in interviews and on social media.
Among his claims were that PCR tests 'were the biggest fraud ever perpetrated on mankind', dying Covid patients in Italy 'were actors' and that the government's alleged interference in people's lives during lockdown was an 'injustice'.
More recently, Le Tissier, who lost his job on Sky Sports' Soccer Saturday in August 2020 after an overhaul and quit as an ambassador for former club Saints, appeared to suggest that the media have lied about the unfolding horrors in Ukraine.
