Marion Bartoli has hit back at Gilles Simon's claims that male tennis players should be paid more than female ones.

Simon argued that men play for longer than women, and that the male game is a bigger draw than their female counterparts'.

"The male players spent twice as long on court at Roland Garros [during the recent French Open] as the women. The equality in salaries isn't something that works in sport," said Simon.

"Men's tennis remains more attractive than women's tennis at the moment."

However, Bartoli has criticised these claims, saying that women put in just as much effort as the men do.

"Over the year, we are a long way from earning as much as the men. [Pay equality] is unique to the grand slams and certain tournaments.

"We put in as much as they do. The physical demands, the training and the investment in ourselves are the same as theirs."

Simon, who is seeded 13th at Wimbledon, is set to face Belgian Xavier Malisse in the second round today.
