Costa Rica win penalty shootout
Costa Rica face Netherlands in quarter-finals
Greece score late equaliser to force extra time
Costa Rica played with 10 men for almost an hour

Whether Barrantes Jnr has trouble staying on his feet or not, well we can only speculate. But his namesake Robben was again the key man as the Netherlands came from behind to beat Mexico earlier on.

Did they know the way? Yes, because they live there.
That was a tough watch. Stiff drinks all round at the break.
Offside from a throw-in! Greece have just ticked off one of my footballing pet hates. Good grief.
Kyle, Liverpool: In what's regarded as the best/most exciting World Cup for years, how ironic if Greece repeat 2004 Euros and go on to win the whole thing! Come on Costa Rica do it for Bryan Oviedo!
Can we have more quality like that please? A stupendous cross.
Other than that it's been poor. Oscar Duarte takes a bad touch, Lazaros Christodoulopoulos nips in to take the ball off him, the Costa Rican pulls him back and gets booked.

"Dimitris Salpingidis gets the run on Junior Diaz and hits it true but what a save! Fantastic from Keylor Navas, his positioning was excellent. But that is what Greece can do in wide areas, the ball in from Jose Holebas was absolutely fantastic."

Greek left-back Jose Holebas delivers a gem of a cross from deep, it cuts out the entire Costa Rican defence, Dimitris Salpingidis steams onto it at the back stick but keeper Keylor Navas somehow keep it out, turning it away with his right knee.
Fantastic reaction save.

Ed, West Sussex: What happened to the Costa Rica that ripped Uruguay apart? Can we have them back and return these imposters please?

"When they get the opportunity Greece are happy to shoot from 35 yards out. One of the reasons they are doing that is they are not getting many runners into the box.
"You can see how they kept eight clean sheets in their World Cup qualifying campaign but you can also see why they've only scored the two goals here in Brazil, against Ivory Coast."
Now listen up Giorgos Samaras - if you go beyond the last defender, you'll be offside. That's twice now the big man has wasted a good break by straying into the red zone.
I agree with you Steve. A frustrating man to watch.
Steve Huish, Surbiton: Giorgos Samaras is one of the most frustrating players of all time. Watching him play for Manchester City was painful. It's OK knocking in goals for Celtic but on the big stage he is sadly lacking.
Image source, Getty ImagesTwo facts about ages that will warp your mind.
Michael Owen was 27 when he scored his last goal for England.
Giorgos Karagounis was 27 when he won Euro 2004 with Greece. The former Fulham man still covers the turf like a racehorse, albeit a quite slow but well-built racehorse. Remarkable engine for a 37-year-old.
John McEnerney:, external Giorgos Samaras will be putting himself about tonight, not just for Greece but for himself. Shop window, no club! Celtic were nuts to let him go.
Thee free-kick comes to nothing and Greece are able to clear their lines. At the midway point of the half it's the Central Americans who have seen 58% of the ball. We've not had an effort on target and are ominously close to Mexican Wave territory.

"Giorgos Karagounis was absolutely done by the skill of Joel Campbell. He and Bryan Ruiz are the players who can do something a little different and bring some magic to this Costa Rica side.
"Greece are comfortable holding their positions but strangely enough it is when they get the ball that they start to look vulnerable.
"Giorgos Samaras has started the game really well, I played up front in that position myself for much of my career and it is a very important job. The way he holds up the ball will allow his team-mates to get the ball out of the danger area, he is a very important player for Greece."
Great decision! Joel Campbell is tripped right on the edge of the box by Greece skipper Giorgos Karagounis, it looks like a penalty, ref Ben Williams gives a free-kick and is proved bang-on correct.
Giorgos Samaras embarks on one of those mazy dribbles that occasionally convince you that under there somewhere there is a really, really good player. But he then falls over his own feet and a team-mate misplaces a pass backwards and the ball is lost 60 yards downfield.
A Greek comedy of errors.
Chuck Papadoupopoulos: Love to see us Greeks give it a good go tonight! Everyone is saying we cannot win, but we have Giorgos SAMARAS!
