Novak Djokovic suffered a quarter-final defeat to Dusan Lajovic at the Srpska Open, admitting to playing below his best. Despite this, the world number one remains optimistic about finding his stride on clay before the French Open in May. Djokovic lost 6-4 7-6(6) against Lajovic, converting just one of 16 breakpoints. The defeat followed his early exit at the Monte Carlo Masters last week against Lorenzo Musetti. Djokovic hopes to improve his form ahead of Roland Garros, targeting a 23rd Grand Slam to surpass the absent Rafa Nadal. Despite concerns over an elbow injury, Djokovic plans to practice and compete in several matches to get into top form for the French Open.
