Both Ronaldo and Ibrahimovic scored at the weekend in defeats as Juventus fell 2-1 at Hellas Verona, while AC Milan threw away a two-goal lead in a 4-2 defeat by city rivals Inter.
“It wasn’t the result we wanted,” said the 35-year-old Ronaldo despite becoming the first Juventus player to score in 10 successive league games, just one game short of the Serie A record.
The five-time Ballon d’Or winner has scored 23 goals in all competitions this season.
Ibrahimovic, 38, has scored three goals since returning to Milan last month.
The Swede headed in the second goal on Sunday after setting up the first, but Inter hit back with four second-half strikes.
“I showed that I can still make a difference, even at 38,” he said.
But Inter striker Romelu Lukaku will be looking to upstage the two other former Manchester United players against Napoli in the other last-four first leg on Wednesday.
Gennaro Gattuso’s Napoli, despite their current slump, ousted holders Lazio in the quarter-finals.
“There’s a new king in town,” a jubilant Lukaku wrote on Twitter after scoring the fourth goal for Inter in Sunday’s derby.
