Igli Tare said the line-up chosen by Lazio against Novara confirms “how much we care about the Coppa Italia.”
The Round of 16 kicks off at 14.00 GMT and the winners go on to face Inter or Benevento.
“The Coppa Italia is a tournament we care about a great deal, which is why we have used our best available line-up,” director of sport Tare told Rai Sport.
He was also asked about the transfer rumours surrounding Lazio during the January window.
“We’ve got to whittle down the squad a bit, because there are too many players. That will be the most important move of the month.
“It’s the media talking about a new signing on the right flank, but we never mentioned it.”
