Martina Navratilova provoked the ire of several of Novak Djokovic's fans after praising the Serb's recent performance against Daniil Medvedev.Navratilova, who has often criticized Djokovic for his vaccination stance, took a different tone after his match against the Russian at the Astana Open on Saturday. The Serb booked his place in the final of the ATP 500 tournament after Medvedev was forced to retire due to a leg injury.Navratilova took to Twitter to praise Djokovic's performance, calling him a "fierce competitor." "Novak Djokovic just showed what a fierce competitor he truly is- lost the first set to Medvedev, won the second set 8-6 in the TB and then Medvedev, out of nowhere, defaults. And it was clear Novak was disappointed as he was in for a fight. He wanted to play," her tweet read.Martina Navratilova@MartinaNovak Djokovic just showed what a fierce competitor he truly is- lost the first set to Medvedev, won the second set 8-6 in the TB and then Medvedev, out of nowhere, defaults.
