Former Real Madrid duo Raul Albiol and Jose Callejon are aiming to secure a draw at the Bernabeu with Napoli as the pair clash on Wednesday night.
The pair moved to Naples in the summer of 2013 following the appointment of Rafael Benitez – who later went on to manage Madrid – and believe a first leg draw would represent a good result for the Serie A outfit.
"Not losing here is a good result. We want to score; that would be important for the second leg," Callejon explained in Tuesday's media conference.
We want to play as we have done for the last year and a half, feeling comfortable in ourselves.
"Raul and I have friends here: [Sergio] Ramos, [Alvaro] Morata, [Dani] Carvajal, Nacho. We've seen them with the national side. I've spoken with Cristiano [Ronaldo] too. We're still in contact with people here."
Albiol added: "It's always hard to play here. It's a tough tie against the defending champions and we know we have to give our all in both games, especially tomorrow in order to still be in the tie in the second leg at home.
"We need to be on it from the off. Ninety minutes here are very hard, we know this and we'll come out tomorrow with this mentality."
