The French Open happens in May and is one of the 4 grand slam tennis events in the year and is after the Australian Open and before Wimbledon. The French Open made news earlier in the year over some controversy surrounding the location of Roland Garros.
The problems the French open has are trying to expand the number of tennis courts, facilities and to accommodate spectators. There is a growing concern that if the Roland Garros event doesn't get access to more land to expand then it might have to relocate outside of Paris. This would be an embarrassing problem for this grand slam and leave a black eye on tennis.
If these problems can't be sorted then this legendary event will have to undergo some extreme changes such as moving from their historic location to a further location from Paris.
