Djokovic announced Sunday that Agassi will coach him at the French Open, which starts next Sunday.
However, it would go some to prevent one of the top five taking the remaining three Grand Slam trophies this year - Nadal remains odds-on favourite for the French, while Murray is fancied at SW19 and the USA, though Djokovic could well be his nearest challenger for both.
"I spoke to Andre the last couple weeks on the phone, and we chose to get together in Paris", Djokovic said. We'll see what (the) future brings.
"We don't have any long-term commitment". "Unfortunately this week you didn't win, but I'm sure as we get closer to Paris you'll be one of the favourites for the title".
Next up is his defence of his title in the French capital, and Djokovic added: "He (Agassi) will not stay the whole tournament".

As the new face of the brand, Novak Djokovic will also appear in a print campaign shot by photographer Jacob Sutton.
"It's definitely an inspired decision", Annabel Croft told Sky Sports. "He's going to stay only to a certain time, and then we'll see after that what's going to happen".
"Andre Agassi is one of the great showmen of the sport, he's such a great speaker and had the press and the fans eating out of his hands".
"Today Novak Djokovic becomes the LACOSTE style ambassador, not only on, but also off the tennis court", the company said in a release. Lendl was back working with Murray again last summer, as the Scot again enjoyed Wimbledon success followed by Olympic glory in Brazil and moved to number one in the world rankings after edging out Djokovic at the season-ending ATP World Tour Finals.
30-year-old Djokovic made it known after the Rome Masters final that he is going to work with Agassi at the upcoming Roland Garros. He's been through everything I have been through right now, not just right now but throughout my career.
Whether or not it ends up developing into a long-term partnership remains to be seen, but for the here and now, Agassi could just prove the flawless tonic as Djokovic looks to climb back above Andy Murray to become world No 1. "He had to go through qualifying and Challenger circuits to try and make his way back up to world No 1, and he did", added Croft.
