Inter missed the chance to close the gap on Serie A leaders Juventus, who lost at Sampdoria, as a first team decimated by injuries and suspensions went down 3-0 at the Stadio Friuli.
Both Moratti and head coach Andrea Stramaccioni had previously urged caution over excessive spending in the transfer window, with the club eager to offload high earners including Wesley Sneijder before bringing in expensive talent.
But following yesterday's events in Udine, and considering the continued absence of nine injured first-team players, Moratti held an emergency meeting at the club's head offices in which he conceded modest reinforcements would be targeted.
He told inter.it: "I can confirm that it will essentially be like that, where the names being discussed are good players.
"But it is also a window where - just like at other clubs - we certainly don't intend to spend too much.
"Listen, I think it's very important to weigh things up when we have everyone back fit because at the moment we're talking about new signings without considering that we might end up buying a player similar to one we already have.
"The most important thing is to get our players on the sidelines back fit. It's hard to assess things when we have 10 or 12 players missing through injury and suspension.
Inter are now nine points shy of Juventus having run the Italian champions close for much of the autumn, but only four points separate the chasing pack after a weekend of shock results.
"The fact the sides around us have dropped points means we're still in there, but we must not worry too much about that, we need to look at ourselves," he added.
"Perhaps I wasn't expecting to top the league but there was always the potential to do well, along with the belief of the players.
"We've got a good team though and, as I've said, it's crucial to get back players who we identified as important at the start of the season."
Inter have already signed veteran striker Tommaso Rocchi for an undisclosed fee, while reports in Italy have linked the club with a move for Chievo goalkeeper Stefano Sorrentino.
