The Nerazzurri chief insists that he will not make a decision about the under-fire coach, who has overseen just one win in eight matches, until after facing Udinese on Sunday
The San Siro outfit currently sit in ninth place in the Serie A table, with no chance of qualifying for a continental competition next season.
Moratti has previously been adamant that he will stand by his young coach, despite the disappointing campaign, but now says that he will make a definitive decision after their clash with Udinese on Sunday.
"It is not yet time to talk about his future, there is still a match left this season, let him work in peace," the 67-year-old told reporters.
"The number of defeats collected this season will not affect the decision on whether or not he will stay, that would be absurd."
Stramaccioni took the reins at the club last season on an interim basis after Claudio Ranieri's sacking and was subsequently awarded the job permanently.
