Inter Milan have a 2-0 lead over AC Milan in the Champions League semi-final, but their rivals are not giving up hope of reaching the final.
The second leg will take place on Tuesday at the San Siro, where Inter will play as the home team.
Inter scored twice in the first leg on Wednesday, thanks to Edin Dzeko and Henrikh Mkhitaryan.
AC Milan manager Stefano Pioli said his team can still turn the tie around.
“We have the quality to overcome this disadvantage,” he said.
“Nobody believes in us now, but we can surprise everyone. We have made some mistakes, but we don’t care about the past.
“Our goal is to win and qualify for the final, which would be an incredible achievement, just like our presence in the semi-finals was unexpected.”
AC Milan, who have won the European Cup seven times, could have winger Rafael Leao back from a thigh injury.
“He [Leao] is improving, as well as [midfielder Rade] Krunic and [winger Junior] Messias,” Pioli said.
“They should be ready for the game.”
Inter are third in Serie A, five points above AC Milan in fifth place, and are aiming to reach the final for the first time since they won the trophy in 2010.
“This is one of the most important games in Inter’s history,” said manager Simone Inzaghi.
“We have an advantage that we earned, but we won’t just defend it. We’ll have to play as Inter, knowing that we face a strong team.
“We’re 90 minutes away from a dream that I and these amazing guys had.
“It will take a calm mind and a passionate heart. That’s the only way to approach games like this.”
Inter might have forward Joaquin Correa available, who was substituted at half-time during their 4-2 win over Sassuolo on Saturday.
The other semi-final will see Manchester City host Real Madrid on Wednesday after a 1-1 draw in Spain last week. The final will be held in Istanbul, Turkey on 10 June.
