Daniil Medvedev had two separate outbursts during his Monte Carlo Masters run. During his match against Gaël Monfils he was a set up when he angrily disagreed with two calls on the baseline and vented his displeasure at the line judge. Umpire Mohamed Lahyani twice came on court to check calls and calm down the Russian fourth seed. Medvedev was 40-15 up but lost his serve and then went 4-1 down in the second set before winning five games in a row to seal a 6-2, 6-4 success and progress to a last-16 meeting with compatriot Karen Khachanov. Medvedev was proved correct both times and after the game, when Lahyani said he would apologise, Medvedev replied: ‘How can you apologise, I lost the freaking game. How did I lose the game when it’s out? It’s out, it’s out.’ The next day, during his match against Khachanov, Medvedev was once again upset by officials after a bad line call while he was serving, this was after he hit a double fault losing his serve. Medvedev told the officials to ‘open [their] fricken eyes’ and questioned who would ‘take action’ against the bad calls.
