Toni Nadal, the uncle and former coach of 20-time Grand Slam champion Rafael Nadal, has joined the coaching team of Canadian Felix Auger-Aliassime.
Nadal, widely known as 'Uncle Toni', coached his nephew from childhood and through his adult career until he stood down in 2017.
He will now join the team of highly-rated Auger-Aliassime, 20, starting at next week's Monte Carlo Masters.
"I never considered before to work for someone else," Nadal, 60, said.
Nadal left his nephew's team after helping him to his first 16 Grand Slam titles to work exclusively at the Rafael Nadal Academy in Majorca.
