Having made a blistering start to what is ************SPAM/BANNEAR************ their fourth World Cup campaign with a shock 3-1 win over Uruguay, the 'Ticos' would be forgiven for keeping the pace high from kick-off as they go in search of another upset.
"Italy have great players like (Mario) Balotelli and (Andrea) Pirlo, who controls all of their play, and we have a lot of respect for them," said FC Copenhagen midfielder Christian Bolanos.
"But we'll hope to benefit from the heavy climate. We are used to playing in those kinds of temperatures."
Italy, who crashed out at the group stage in 2010, launched their bid for a record-equalling fifth title with a crucial 2-1 win over England in Manaus last week in their Group D opener.
But the four-time champions were given notice following Costa Rica's shock win over 2010 semi-finalists Uruguay that a match they would have been widely expected to dominate may be more difficult than first imagined.
"They'll be fired up after their win," said De Rossi. "If they had lost 4-0 then we might have underestimated them, but now there's no chance of that."
However De Rossi added: "But I hope, and I'm sure, we can beat Costa Rica and secure our ticket to the second round."
A second win for Italy would provide a huge boost ahead of their final group clash against Uruguay, but coach Cesare Prandelli faces selection dilemmas.
