Tough-tackling Roma midfielder Daniele De Rossi has underlined Costa Rica's likely advantage in the sweltering conditions in Recife, where he said Italy were "dying from the heat" last year during the Confederations Cup.
Having made a blistering start to what is only 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.
"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.
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.
AC Milan's Matteo De Sciglio, who normally plays at right-back, is not expected to recover in time from a thigh knock, while Andrea Barzagli and central defensive partner Gabriel Paletta, who failed to convince against England, could both start on the bench.
