Ramon Diaz parted company with Argentine champions River Plate on Tuesday, just days after leading them to a 35th league title, the club announced.
"During a meeting with the club's directors, the coach let it be known that he had achieved his objectives, which is the reason he decided to leave," the club said on its website.
Former midfielder Diaz, who had two spells as a player at River Plate as well as stints in France and Italy, helped the Argentine giants end a six-year wait -- that also saw them relegated to the second division in 2011/12 -- for a trophy.
A 5-0 victory over Quilmes saw them finish five points clear of fierce rivals Boca Juniors in the Torneo Final, the second of two league championships played in the Argentine season.
The 54-year-old is the most decorated coach in River Plate history having won seven national titles as well as the Copa Libertadores. He also won the domestic league fives times as a player.
Former Uruguay international Enzo Francescoli, another ex-River Plate player, is tipped to succeed Diaz.
