The Serbian confirmed on Sunday (May 21) after his defeat to Germany’s Alexander Zverev in the Rome Masters final that he appointed the American, who won the title at Roland Garros in Paris in 1999 to complete a career Grand Slam, as his new coach.

It followed a mutual agreement made earlier in the month between Djokovic and Marian Vadja which saw the latter end his association with the player after 11 years together.

Looking ahead to the clay court tournament, which begins tomorrow, Djokovic, who has won 12 Grand Slam singles titles, said he was delighted to have Agassi, the Olympic champion from Atlanta 1996, by his side.

“The change that I have experienced in the last three or four weeks, separating with the team that I was with for 10 years and now kind of creating a new team, creating a new vibe, feels exciting,” the 30-year-old said.

“it feels right at this moment because I was struggling a little bit on the court over the last five, six months, trying to redefine myself and rediscover what kind of approach is the right one.

“We all felt we needed a change, we needed to go our separate ways.

“So right now, I feel much better on the court.”

Djokovic heads into the second Grand Slam tournament of the year as the number two seed behind world number one Sir Andy Murray, who the Serbian beat in last year's final to complete a career Grand Slam and became the third male to hold all four major titles at the same time along with Don Budge of the US and Australian Rod Laver.

The double Olympic gold medallist from Britain faces Russia’s Andrey Kuznetsov in the opening round while Djokovic has been drawn against Spain’s Marcel Gronollers, with both matches taking place on Monday (May 29).

Fourth seed and nine-time French Open winner Rafael Nadal is considered the favourite for the tournament and plays France’s Benoit Paire in the first round.

Tomorrow’s action will see Petra Kvitova of the Czech Republic appear first up in the women’s singles competition on Philippe-Chatrier Court as she plays her first match since being stabbed in the left hand by an intruder at her home in December.

She faces Julia Boserup of the US, with play due to start at 11am local time.

Kvitova’s match will be followed by the top seed and world number one Angelique Kerber of Germany, who faces Russian Ekaterina Makarova.

Reigning champion Garbine Muguruza is not scheduled to play tomorrow.

The Spaniard faces a tough test when she does appear on court as she has been drawn against 2010 champion Francesca Schiavone of Italy.

The tournament is due to run until June 11.
