Costa Rica coach Jorge Luis Pinto has stressed that the Group D winners will be ready for any opponent in the World Cup knockout phase.
Pinto's men will meet Greece in the round of 16 after Fernando Santos' side snatched second spot in Group C with a last-minute winner against Cote d'Ivoire.
"I'm delighted we've topped the group. We are prepared to face whoever comes and we will face them with great confidence," he said at at a press conference after his side's scoreless draw against England on Tuesday.
"Our potential rivals from Group D will be difficult as they're experienced, but we'll approach them as we have been doing.
"We're a well-balanced team with good tactics."
Costa Rica retained their unbeaten status against England after earlier victories over Uruguay and Italy and Pinto feels Tuesday's encounter was an even game.
"It was an even game today against an opponent who was looking for its first win."
Costa Rica last made it to the round of 16 in 1990 and will take on Greece while Group D runners-up Uruguay prepare to meet Colombia.
