Though the Italian resumed for training this week, he is now understood to have left his post with 12 months remaining on his contract, with former Napoli manager Maurizio Sarri set to take over from his Italian compatriot at Chelsea.
Conte, 48, led the west London club to Premier League title glory in a successful first season at the helm but his second campaign proved far less harmonious and although they lifted the FA Cup in the spring, they could only finish fifth in the Premier League.
Napoli president Aurelio De Laurentiis announced on Wednesday that “Sarri is close to being new Chelsea manager.”
Former Chelsea captain John Terry has also posted a message on his Instagram account, saying: “Great man, Great manager. I wish you every success in the future.”
Chelsea are yet to make a move in the summer transfer market, with uncertainty over their management team delaying their dealings.
Furthermore, Brazil international Willian could be on his way out of the club, with Barcelona understood to have returned with an improved £53m bid for him.
Playmaker Ede Hazard could also follow suit with reports linking him with a move to Real Madrid to replace the recently departed Cristiano Ronaldo.
