Former tennis player Martina Navratilova did not hold back while confronting a critic on social media on Sunday.
One user accused the Czech-American of using steroids back in her playing days, which she did not take lightly.
"@Martina steroids you know about but it was OK because you were different," a tweet read.
The former World No.1 made her feelings clear and stated that she did well in her playing days as she was just better than those around her.
"Careful here Bill- you are treading on very thin ice… I was just better," she added.
The 65 year-old is considered to be one of the greatest tennis players of all time. She has won a total of 59 Major titles, with 18 of those being singles. She also holds the record for winning the most singles tournaments (167), more than any male or female. She has also won the most (9) Wimbledon ladies' singles titles.
