Djokovic's awesome response to opponent's epic shot

Novak Djokovic again showed why he's one of the best sports in tennis with a classy response to his opponent's insane winner at the French Open.

The defending champion made a winning start under new coach Andre Agassi, cruising past Spain's Marcel Granollers in the first round.

But the point of the match undoubtedly went to the Spaniard and Djokovic was quick to congratulate his opponent on the remarkable winner.

The Serb was already two-set-to-love up against Granollers when he had the Spaniard on the rack at 2-1 down in the third.

After being forced to the net, Djokovic looked to have the point won when he scrambled to return a drop shot just over the net.

Incredibly though, Granollers produced his own moment of magic to reach the ball and send an unstoppable winner around the net from outside the doubles lines.

Both players looked at each other in disbelief and a huge smile beamed from Granollers as Djokovic came to the net to give his opponent a deserved high-five.

12-times grand slam champion Djokovic parted company with his entire coaching team earlier this month after a string of disappointing results before inviting American great Agassi to work with him during the French Open.

Agassi, however, will only stay for the first week of the tournament due to prior obligations, Djokovic said.

The 30-year-old Serbian, without a tour title since January, found little resistance from 77th-ranked Granollers, grabbing two breaks early on in the 6-3 6-4 6-2 victory.

"It was different for me being here this time because being defending champion gave me a lot of relief," Djokovic told reporters.

"I wanted to start off well, engage all engines in the right way which I have done."

With Agassi, sporting a black T-shirt and sunglasses, quietly sitting in the stands along with the Serb's entourage, it was a similar story early in the second set with the world number two returning everything Granollers tried to throw at him.

He again went 4-1 up before a wobble saw him fail to convert eight set points at 5-3.

"A set up and 4-1 up, when I had him on the ropes I just played very bad games," he said. "That's the only thing that wasn't great for me."

Djokovic, though, kept his cool to earn the second set and capitalised on the Spaniard's accumulating mistakes in the third set to seal victory on his first match point.

With eight-times grand slam champion Agassi making a fast exit from the stands at the conclusion of the match, Djokovic heaped praise on his new coach.

"It is an incredible honour and good luck to have him with me on the team," Djokovic said.

"Every day is special with him. I am learning something every day."

The Serbian said Agassi, who started working with Djokovic only days ago, would leave at the end of the week.

"I will try to use the time with him as best as I can. Plenty of information, plenty of things to process," he said.

"I think this is exactly what I needed at this moment, a person like him who understands the reactions as a tennis player and a person."

"I changed everyone (coaches).

"But I will not change my wife. My wife never."
