Mancini has led Inter to just one victory in five attempts in all competitions since his return to San Siro last month - with just one point accrued from a possible nine in Serie A.
With Inter languishing in the bottom half of the league, key first-teamers like Mauro Icardi and Fredy Guarin have been linked with a move away from Inter.
However, Mancini is bullish over the pair's status, insisting neither the Argentinian or Colombian will be used to fund any moves when the window re-opens next month.
He told reporters: "New players? When I think about the team, it is normal that we need different players for playing in a different way.
"I am not sure, but I think that the club may sign new players.
"Guarin and Icardi up for sale? I don’t think so, I think that we have just to buy some players that we are currently missing."
"Did I talk with Balotelli? The last time was two years ago, before a match in London," Mancini explained.
"I support Mario, I hope that he will be happy one day."
