Giampaolo took over this summer from Gennaro Gattuso, who departed the club after a season and a half at the helm.
A statement on the club’s official website reads: “AC Milan announces that it has relieved Marco Giampaolo of his role as coach of the first team.
“The club intends to thank Marco for the activity carried out so far and wishes him the best professional successes.”
DAILY POST reports that the 52-year-old took his place in the San Siro hot seat after three years in charge of Sampdoria, but was unable to replicate the success he enjoyed at the Stadio Luigi Ferraris.
Giampaolo’s last game in charge was a 2-1 win over Genoa at the weekend, but that result wasn’t enough to save his job.
That win over Genoa was preceded by three consecutive defeats, with Milan falling to city rivals Inter before also losing to Torino and Fiorentina.
With the arrival of the international break, Milan will have nearly two weeks to search for a new manager to take over from Giampaolo.
Luciano Spalletti, who left Inter at the end of last season and was replaced by Antonio Conte, has been mentioned as a possible candidate.
Stefano Pioli, who most recently managed at Fiorentina, is also considered a possible successor for Giampaolo, as is former Roma and Marseille head coach Rudi Garcia.
