Agassi's first task will be to restore Djokovic's confidence after it took another hit with a 6-4 6-3 defeat to 20-year-old rising star Zverev. Earlier, Djokovic overcame having to play twice in a day before cruising into the final of the Rome Masters with aruthless 6-16-0 win over Thiem.
A long backhand by Djokovic, who will celebrate his 30th birthday on Monday, subsequently ensured victory to his highly-rated opponent.
Earlier this month, Djokovic split with Marian Vajda, his coach of 11 years who helped him rise and develop into a 12-time Grand Slam victor.
"He's a legend of our sport", Djokovic told reporters after losing in the final of the Internazionali BNL d'Italia in Rome.

It is not a long-term commitment, but Becker, who coached Djokovic to six Grand Slam titles in three years, has hailed it as an "excellent choice". "It's just us trying to get to know each other in Paris a little bit", added the 12-time Grand Slam champion. On the court, he understands the game amazingly well.More news: Low gas prices will mean more road trips this summer
There was also a surprise in the women's final as eighth seed Elina Svitolina of Ukraine beat world number four Simona Halep of Romania in three sets to secure a WTA Tour-leading fourth title of the season.
Novak Djokovic hadn't won any break point in this event, and that is only the third time in his career to perform like this, when he appears in the finals of Masters. "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". "We are both excited to work together and see where it takes us".
"I think I can be proud of myself for handling the pressure, because I played some tough matches here".
The world number two has won just once this year and lost his spot at the top of the rankings to Andy Murray late in 2016.
Three-time Wimbledon victor Boris Becker, who left the Djokovic coaching set-up at the end of December after three years by his side, welcomed the news, saying on Twitter that hiring Agassi was an "excellent choice".
