Leonardo's team have failed to keep pace with city rivals Inter in Serie A
AC Milan boss Leonardo has announced he is leaving the club by mutual consent after just one season in charge.
The 40-year-old stepped up from his role as Milan's technical director to succeed Carlo Ancelotti last May when the Italian left for Chelsea.
Leonardo struggled to improve an ageing team, with the club currently third in Serie A with a game to play.
"We mutually announce that we are parting," said Leonardo, who had no previous managerial experience.
The Rossoneri, who have not won the league title since 2004, are 12 points behind Jose Mourinho's Inter Milan and 10 behind Roma after 37 games of their 38-match season, while they crashed out of the Champions League at the last-16 stage with a 7-2 aggregate defeat by Manchester United.
With a three-point lead and superior goal difference over fourth-placed Sampdoria, however, Milan look certain to secure Serie A's third automatic Champions League spot for next season.
The Brazilian, who was joined by Milan's vice-president Adriano Galliani for the news conference, added: "We're here together to communicate our separation by mutual consent in a calm and serene way, as has been our relationship throughout the years.
