"I'm not worried", said the Italian. "The flu is not only on the pitch, it's everywhere. I'm not worried. We take all the precautions and we want to think about playing, that's it.
"I know very well what I have to do if I have the flu. It's not a medical prescription. It's my grandmother's prescription: milk and red wine. Fantastic."
Ancelotti will make changes against Bolton, though, adding: "We have some players injured at this moment who cannot play tomorrow. Jose Bosingwa, Ashley Cole, Yuri Zhirkov, Sam Hutchinson and John Obi Mikel are not ready to play. Maybe they can return next week in the squad.
"I want to rest John Terry, Ricardo Carvalho, Nicolas Anelka and Petr Cech. Other players will be in the squad tomorrow.
Ancelotti insisted that Chelsea were taking the competition seriously, adding: "It's important because it's the first final of the season and we want to be there in that final. It's the first title in the season.
"We have a good opportunity tomorrow. We will change the team, but we will still put on the pitch a very competitive team."
