A double by Colombian Brayan Perea handed holders Lazio a place in the Coppa Italia quarter-finals as they beat fellow Serie A side Parma 2-1 in Rome.
Perea, 20, grabbed the winner in stoppage time for a virtually second string Lazio side.
He had opened the score only for Frenchman Jonathan Biabiany to equalise for the visitors.
Lazio, who have won the trophy five times in the past 16 seasons, will play either Napoli or Atalanta -- who play on Wednesday -- in the last eight. AC Milan will face second division side La Spezia.
