The 15th seed suggested Medvedev has a close network he can turn to after Boris Becker urged him to get ‘professional help’

At Wimbledon in 2017, Medvedev was fined after emptying his wallet and throwing coins at umpire Mariana Alves following a five-set loss to Belgium's Ruben Bemelmans. He disputed a series of controversial calls and said after the match "it was very hot out there" and couldn't remember if he'd asked for Alves' removal.

For the number of Daniil Medvedev meltdowns the tennis world has seen, Monday night on the court of Louis Armstrong hit differently.
