Paris - Novak Djokovic began his partnership with Andre Agassi with victory on Monday but the American legend definitely won't be around if the Serb successfully defends his title.
Agassi, the 1999 Roland Garros champion and eight-time major winner, had only committed to just a "few matches" with the world number two.
Now Djokovic has confirmed that should he make the second week of the tournament, he'll be flying solo.
"Well, he's going to stay, I hope, till the end of this week. Then he has to leave, because he has already scheduled some things that he cannot reschedule," said Djokovic after claiming a 6-3, 6-4, 6-2 win over Spain's Marcel Granollers.
"So that's all. I'm going to try to use the time spent with him as best as I can, as best as we can."
Monday's win - his fourth in four meetings with the Spaniard - was the perfect way to mark his 50th successive Grand Slam appearance.
But there is still work to do for the 30-year-old whose form has dropped off since he completed the career Grand Slam in Paris 12 months ago.
"Andre has left already. He's waiting for me for a serious talk," joked Djokovic on Philippe Chatrier.
Djokovic dropped served four times and required nine set points to claim the second set against a player who had only won 10 games in their previous three encounters.
The Serb, seeking to become the first man in the Open era to win all four majors on at least two occasions, eventually wrapped up matters after two and a half hours on a hot and muggy centre court.
Agassi, 47, has kept a relatively low profile since his arrival in Paris, giving just one television interview.
On Monday, as he watched Djokovic play, he was greeted by Boris Becker who gave up coaching the Serb in December after three years together.
"I can see only positives to now. But it's hard to say whether there is significant difference on the court, because it's only a few days that we are together," added Djokovic.
The 12-time major winner split with with long-time coach Marian Vajda earlier this month and named Agassi after he lost to Alexander Zverev in the Rome Masters final.
"It's going to take a little bit of time. I'm patient, and for us this is a great way to start our collaboration and friendship and get to know each other and then see where it takes us."
Next up for Djokovic is a clash with Portugal's Joao Sousa who beat Janko Tipsarevic of Serbia 4-6, 7-6 (7/3), 6-2, 6-2.
