Joel Campbell has warned Costa Rica's FIFA World Cup rivals that they are confident of beating anyone after coasting into the last 16.
The South American nation were not expected to make an impact at the showpiece in Brazil, but they have emerged as a surprise package.
Victories over Uruguay and Italy sealed their progress from Group D with a game to spare and they only need a point against England on Tuesday to win the group.
Arsenal striker Campbell, was scored in the 3-1 opening-game victory over Uruguay, has no preference as to who Costa Rica face after their clash with England as he believes Jorge Luis Pinto's side have nothing to fear.
"We are not thinking about who we get in the last 16," he said.
"It does not matter to us. We have been in a group with three champions of the world and we have shown that we can beat anyone.
"We always believed we could do this. Football is not decided by the shirt you are wearing. With work and effort, you can win against anyone.
"We are very satisfied, very happy with what we have achieved but we will keep working to do more.
"This is unforgettable. We are part of history. Nobody would have put a single dollar on this team qualifying but there you go.
"It can change football in Costa Rica. These are the best days of my career."
The winners of Group D will face the runners-up in Group C, with Colombia, Ivory Coast, Japan and South Korea competing in that pool.
