Three-time Grand Slam champion Andy Murray says he "won't quit" tennis despite being in a "terrible moment".
The Briton, 36, is winless in 2024 after Monday's first-round loss to Benoit Paire at the Open Sud de France.
Murray also suffered a first-round exit at the Australian Open, while his last ATP Tour victory was in October.
On Tuesday, he responded to a BBC reporter's post on X, which asked when Murray should "call time on an extraordinary career".
The post linked to an article which said while the Scot's status as a legend was secure "at what point does bravely soldiering on start to damage his legacy?"
"Tarnishing my legacy? Do me a favour," two-time Wimbledon champion Murray wrote in reply.
"I'm in a terrible moment right now, I'll give you that.
"Most people would quit and give up in my situation right now. But I'm not most people and my mind works differently.
"I won't quit. I will keep fighting and working to produce the performances I know I'm capable of."
The article asked whether Murray's "refusal to back down from a challenge" was doing him "more harm than good".
World number 49 Murray has suffered nine defeats in 13 matches since the start of the US Open in August.
The former British and world number one defied the odds to return from hip replacement surgery in 2018.
However, since losing to Daniil Medvedev in the Qatar Open final last year, he has not won more than two matches at any tour-level event and is about to drop out of the world's top 50.
Murray said in Melbourne earlier this month that there was a "definite possibility" he had played in his last Australian Open.
