Legendary former Inter goalkeeper Julio Cesar feels that this current Nerazzurri team will have to emulate that of the 2009-10 season in their trip to the Camp Nou to face Barcelona tomorrow.

Speaking to Milan-based newspaper Gazzetta dello Sport in an interview published in today’s print edition, the Brazilian also spoke about Andre Onana in the Inter goal.

Inter got the job done against Barcelona last week with a 1-0 win, but repeating this will be anything but easy.

The Blaugranas are one of the most formidable teams in Europe at the moment, and will be desperate to take three points and keep the race for knockout round qualification open.

Barcelona had also been among the very best team’s in the world when Cesar and Inter travelled to face them in 2010.

That time around, the Nerazzurri were able to fall to defeat and still progress on aggregate, but it was a loss that felt like a win.

In any event, as Cesar says, it was a result that took a great deal of composure in the toughest of environments.

“This is a very different game from that,” Cesar said, “we can’t put a Champions League semi-final on the same level as a group stage match.”

He continued that “Today’s Inter will have to keep their nerve like us, that’s clear.”

Asked if he had any advice for Onana, the Brazilian replied “What do you want me to tell him? He will already have his own advice.”

“By the way, he came through the ranks at Barcelona and will have many memories and additional motivation.”

“If before the number one danger was Messi, now in attack they have another phenomenon in the form of Lewandowski,” he added, “I can only hope that he is able to do what I did, and keep Lewa quiet.”

Asked if he has any thoughts on the changing of the guard from Samir Handanovic to Onana, Cesar responded that “I won’t go into Inzaghi’s choices, Onana is a goalkeeper of great potential.”

“But I’d say he has to make the most of the opportunity to play and train every day with a real champion like Handanovic.”
