The Nerazzurri are still smarting after their 2-1 home defeat to Juventus last night.
"We have to keep going, taking it one game at a time, so it takes patience," Moratti told Sky Sport Italia.
"I am a little disappointed at last night. The first half was wonderful, the second less so, but in any case the problem is not Ranieri."
The patron was asked whether there will be another revolution during the transfer window.
"We'll see how we're doing in January."
