Some tennis players who are not from France say it is hard to play against French players at the French Open. They say the crowd is very loud and not friendly, like at a football game. The crowd shouts and makes noise, so last year the people who plan the tournament stopped people from drinking alcohol in the stands. One player said it was "very bad." The person in charge of the tournament, Amélie Mauresmo, said they have more security now. The referees can also stop people if they are not acting well. But not all players are bothered by the noise. One player from Belgium said it is normal. A French player said it is hard to play at home because of the pressure, but players should try not to listen to it.
