Italian giants Juventus fired Maurizio Sarri as coach in just one season.
Sarri led Juventus to their ninth consecutive Serie A title, but Lyon knocked him out of the Champions League in the round of 32.
Juventus won 2-1 in Turin on Friday but on the road the French continued to score.
Sarri Italian, 61, was assigned to a three-year contract last summer after a year at Premier League club Chelsea.
Juventus have lost three of their last four league games and ended up just one point ahead of Inter Milan.
They were also beaten by Napoli in the Italian Cup final after football resumed in the country following the coronavirus shutdown.
Juventus is a two-time European Cup / Champions League winner but has not lifted a trophy since 1996.
In a statement from the club, Sarri thanked him for “writing a new page in Juventus history”, adding that it was “the culmination of a personal path that led him to ascend all divisions of Italian football”.
