Some tennis players who are not French have complained about the French Open. They said the crowd was not friendly when they played against French players, like at a football game. The crowd shouted and made noise, so last year, the people who organize the tournament stopped selling alcohol in the stands. One player said it was "very bad." The person in charge of the tournament said they have more security now. The referees can also stop people who are acting badly. But some players don't mind the noise. One French player said it is normal to feel pressure when you play at home, but players should try not to think about it.
