Mouratoglou: 'Djokovic's loss is not worth worrying'

"Djokovic used to lose like that last season and still play well after that," former Serena Williams coach said in an interview with Eurosport on April 15. "The two-month break without playing has cost Djokovic. This is normal for any tennis player."

Djokovic attended the Monte Carlo Masters after a long break after losing to Daniil Medvedev in the semi-finals of the Dubai Championships on March 3. He got off to a good start in Monte Carlo when he overcame Ivan Gakhov in the second round. But the Serbian player soon stopped when he lost 4-6, 7-5, 6-4 at the hands of Lorenzo Musetti in the third round.

Some sources from French journalists believe that Djokovic injured his elbow after a training session, causing a marked decrease in his serving ability when playing Musetti. According to Mouratoglou, if the injury is not serious, Djokovic is fully capable of winning Roland Garros.

"I don't coach Djokovic so I don't know what he trains and thinks about," Mouratoglou said. "But he definitely needs to go to the tournaments before Roland Garros to warm up. When he's at his best, Djokovic doesn't have many opponents at Grand Slam, although I see young talents making rapid progress."

Mouratoglou, who has been with former number one Serena Williams for a long time, has coached Stefanos Tsitsipas and is now working with Holger Rune, a recent Monte Carlo Masters finalist. Mouratoglou believes that Djokovic's biggest risk at Roland Garros is the sudden sublimation of a young talent.

Djokovic has returned to Belgrade to prepare for the ATP 250 Srpska Open. This award is directed by his younger brother – Djordje. Djokovic is expected to attend two Masters 1000 in Madrid and Rome, before going to Roland Garros.
