Kostas Manolas sees no reason why Greece will be unable to prolong its FIFA World Cup campaign by beating Costa Rica on Monday (AEST).
Georgios Samaras's last-gasp penalty secured Greece's place in the last 16 at the expense of Cote d'Ivoire, as the African nation was consigned to a 2-1 defeat in Fortaleza.
Greece can now look forward to a second-round World Cup clash for the first time in its history and Costa Rica, another surprise package, lays in wait.
Defender Manolas believes Fernando Santos's side will end Costa Rica's tournament if it can maintain the standard it set in its final Group E clash.
He said: "We are all set and we're going to match with Costa Rica just to qualify.
"I believe that if we play as in the last game against Ivory Coast will be able to qualify."
Costa Rica finished top of Group D after beating Uruguay and Italy, then drawing against England.
