Inter now are within two points of leaders Milan.
The Scudetto race is now wide open and the derby on April 2 could be decisive, as the top two go head-to-head.
"I fear Milan's experience and their cool heads. They always know how to behave in these big games," said Moratti.
"It will be a fascinating derby, but not decisive, and I hear some people saying we are the favourites because of current form. I fear these predictions."
