Now with four-time champions Italy in their sights, Jorge Luis Pinto's men can all but secure their place in the last 16 of the competition with a game to spare courtesy of a victory over their European counterparts in Recife on Friday.
The Azzurri, though, will also be full of confidence for this encounter, having disposed of England at the weekend with a 2-1 win in the heat and humidity of Manaus.
What's more, head coach Cesare Prandelli will have been boosted by the return to training of goalkeeper and captain Gianluigi Buffon. The 36-year-old missed the clash with England because of an ankle complaint, but could return against the Costa Ricans.
Full-back Mattia De Sciglio is also thought to be nearing a return to action, but the match may come too soon for the AC Milan defender.
As for Costa Rica, Pinto has been tipped to pick the same side that started against Uruguay, which will mean that Arsenal's Joel Campbell will operate as a lone centre-forward once again.
These two nations have met only once before back in 1994, with the Italians running out 1-0 victors thanks to a goal from Lazio centre-forward Giuseppe Signori.
