(Kakashi even says that Itachi's techniques take more chakra than they normally should in Part II.)

where it was said that?I really don't remember,tried to search on google but didn't find anything.In my opinion it was implied that itachi chakra reserves were low due to his sickness.But if you tell me the chapter I can check the information.
