Andrea Agnelli has written an open letter to Antonio Conte, saying his departure leaves the Juventus president "enormously sad".
The club confirmed on Tuesday that the 44-year-old has departed the club after handing in his resignation, bringing an end to a successful stint in which the Italian giants won three consecutive Serie A titles.
And Agnelli praised the coach for his service and returning silverware to the club in each of his three years in charge.
"Dear Antonio, you were a great leader for our players and this news leaves me enormously sad," wrote Agnelli wrote on the Juventus website.
"I think of the three years we spent together, three years that brought us to write history with this club: three consecutive Scudetti, two Italian Super Cups, but above all exponential growth."
The 38-year-old reassured fans that the club will continue to improve instead of regress without Conte.
"Only two months have passed since the last great victory and Juventus must continue their journey.
"This club is gifted today with a young, ready and cohesive group of directors who over the years have been able to find the ambition and determination to achieve any target.
"Juventus begin again from a very talented and professional group of athletes, who will be at the disposal of the new coach in order to continue writing the present and the future."
