Ranieri says chairman Shahid Khan will back him with more players in the January transfer window if he needs them - despite the club spending more than £100m in the summer.
"I spoke with the chairman about this," Ranieri said. "There are some people that are working (on recruitment) and then they put to me some players.
"They show me the name and after I have to choose who is the right player for us - I am happy with that.
"For now I have to work with these players. I haven't met them all yet because of the international break - but already I love them. I want them to bring their best.
"After, if there is something, I can say to the chairman 'I need another player because I need this kind on the team' - that's another thing."
