French Open night sessions will remain despite the reservations of Rafael Nadal and Novak Djokovic whose epic quarter-final clash ended at 1:15 on Wednesday morning in front of thousands of shivering fans, many of whom were huddled in blankets to keep out the biting cold. 

“Night sessions will stay, but obviously we are going to see whether we move the starting time or not,” admitted tournament director Amelie Mauresmo, a two-time major winner and former world number one.
