The Italian side have performed below expectations in their Serie A campaign this season, going into this weekend's fixtures in seventh place. Besides crashing out of the Coppa Italia at the hands of Napoli earlier in the year, the Nerazzurri also lost their Champions League round-of-16 tie with Olympique de Marseille on Tuesday.
A recent string of disappointing results have led to fans calling for manager Claudio Ranieri's resignation, but Moratti believes that improvement could come with a squad overhaul.
"A wise idea might be that of starting to think about the future not in immediate terms, but by building a team that is essentially young," he told the club's official website.
"In addition to the ability of new players with fresher legs, we also need experience. Many will remain, and we'll also get some new players."
However, the Italian warned that such a drastic change in playing staff will likely lead to a lack of short-term success.
"It would be wise to rebuild from the foundation without the idea of immediately obtaining big results, and hoping the acquisitions you make will turn out to be the right ones."
