LONDON (Reuters) - World number one Novak Djokovic leapt to the defence of great rival Roger Federer on Monday after claims that the Swiss enjoys preferential treatment on Tour.
Frenchman Julien Benneteau caused a stir during an interview on French radio station RMC Sport on Sunday in which he said tournament referees were often kinder to Federer when it came to scheduling his matches.
