Alex tells Napoli that Milan are “very different” to when they lost 4-0 and compares Gonzalo Higuain to Zlatan Ibrahimovic.
It kicks off at the Stadio San Paolo on Monday at 20.00 GMT, click here for a match preview.
“It was difficult for us to forget that night,” the defender said of their 4-0 home demolition in October.
“The result was really hard on us, especially because it was at San Siro. Now we must give a response in the League, to prove we are very different to the side people saw in that game.
“We will need to be very wary, as Higuain is right now one of the best strikers in the world. He can make the difference at any moment in a game.
“I played with Ibrahimovic and I can tell you Higuain has the same character and charisma,” Alex told the Corriere dello Sport.
“Gonzalo is unpredictable and very quick. We need two of us to stop him – one anticipates the ball, another is behind him ready to intervene.
“We also need to keep an eye out on Lorenzo Insigne and Jose Callejon. We worked on this in training, so we can face the Napoli forward line in the best possible way.
“It’s difficult, but if we want to finish third in Serie A then we must put in a great defensive performance at the San Paolo. We tend to score at least one goal.”
Today marks the 30th anniversary of President Silvio Berlusconi buying Milan, but it is also Coach Sinisa Mihajlovic’s birthday.
“Our President deserves a special gift for all that he has done for Milan over the years. We will put in a great performance and play to win.”
