Inter Milan have sacked coach Gian Piero Gasperini after just five matches and three months in charge.
The ex-Genoa boss, 53, lost four games, taking just a point from Roma, and his side sit 17th in Italy's Serie A.
His last match was a disastrous 3-1 defeat on Tuesday by Novara, who were only promoted last season.
Inter also lost 1-0 to Trabzonspor at the San Siro in the Champions League and were beaten by AC Milan in the Italian Super Cup in August.
Gasperini was a replacement for Leonardo, who is now at Paris Saint-Germain.
A statement from Inter read: "Inter announces that today's training session has been carried out by Daniele Bernazzani and Giuseppe Baresi.
"The club wishes to thank Gian Piero Gasperini for the effort shown during his tenure and manifests its true disappointment for the interruption of the relationship with the coach."
Gasperini told Inter Milan's official website: "In the end, the results are the ones that determine everything. I am very disappointed. It's a pity that our relationship had to be interrupted."
Inter president Massimo Moratti questioned Gasperini after the defeat at Novara.
He said: "When you lose in the manner that we did against Novara, there is nothing positive to take from that.
"Gasperini did not seem to be in control."
After that, Gasperini hit back: "Moratti has declared that I don't have the support of the players.
"The rapport with the group is optimum. If the problem is the coach, then it has an easy solution.
"If, instead, as I believe, the problem is another one, then we must resolve it through work."
Inter have yet to announce who will replace Gasperini. They travel to Bologna on Saturday before taking on CSKA Moscow in Russia in the Champions League four days later.
