World number two Novak Djokovic said Andre Agassi will be his new coach after the Serb lost in the Italian Open final to Alexander Zverev.
The 12-time Grand Slam winner parted company with his entire coaching team earlier in May.
Former world number one Agassi will be with Djokovic in Paris for the French Open, which starts on 28 May.
The news was confirmed after German Zverev, 20, stunned Djokovic 6-4 6-3 to win in Rome.
In the women’s event, Ukraine’s Elina Svitolina triumphed with a 4-6 7-5 6-1 win over Romania’s Simona Halep.
