Novak Djokovic fights off nerves to avoid upset against teenager Lorenzo Musetti

Novak Djokovic fought off nerves and the teenage exuberance of Lorenzo Musetti as the old guard put the youngsters in their place once again at Roland Garros. This was a first chance for 19-year-old Musetti, playing in his maiden grand slam, to test himself against one of the sport's big beasts and for two sets the Italian was mesmerising before fading dramatically, pulling the plug trailing 6-7 (7) 6-7 (2) 6-1 6-0 4-0.
