Inter Milan have sacked Claudio Ranieri in the wake of a disastrous run of form.
Inter president Massimo Moratti claimed earlier on Monday Ranieri was likely to remain as manager until the end of the season.
However, Moratti has now decided to axe the former Chelsea chief with Inter languishing in eighth spot in Serie A.
Inter have won just one of their last ten games with Sunday's defeat to Juventus appearing to be the final straw for Moratti.
Ranieri took charge of Inter in September as a replacement Gian Piero Gasperini, but he has been unable to transform Inter's fortunes.
Inter have appointed youth team coach Andrea Stramaccioni as Ranieri's replacement after he guided Inter to success in the NextGen Series.
A statement from Inter read: "President Massimo Moratti and everyone at Inter Milan would like to thank Claudio Ranieri and his staff for their professionalism, dedication and honesty during their time in charge of the team.
"Inter also announce that they have entrusted the team to Andrea Stramaccioni, the coach who won the first edition of the Next Generation Series."
Former Chelsea boss Andre Villas-Boas has been strongly linked with taking up the manager's role on a permanent basis at the Giuseppe Meazza.
