The Greeks are through to the last 16 of the World Cup 2014 and so right we have predicted it the last time. The correct score 2-1 against Ivory coast matched at price up to 16.00 (15/1) and Both teams to score had an awesome price up to 2.00! Thanks for your kind words and messages. 
Mr Fernando Santos finally realised that Jesus George Samaras can't do his miracles on the left wing and George shined as a forward by creating the first goal, winning a penalty and scores the second goal. The team played so much better without Katsouranis and the whole Greek nation is shouting to Mr Santos to not starting him today. 
If this happens, then George Karagounis will start the game for sure. Having said that, looking back to the game against Ivory Coast, I do agree that Karagounis inspired the team with his experience however, all the rest players had to do the running for him. In my opinion, except the fantastic shot he had on the second half and a couple good passes, he did not do much. In this case, Greece was lucky enough because Ivory Coast did not focus on controlling the middle field but trying to push forward. Similar things I have to say about Dimitris Salpingtidis. What a waste on the right wing having a striker trying to mark most of the times and he has no stamina and power to go forward when Greece has the ball. It might sounds cruel but what I am trying to say is.... Mighty Greeks were playing 9 against 11 most of the game against Ivory Coast and they did it!
Costa Rica is a different story. They will not go all attack like Ivory Coast. They play passive and careful football, defending themselves with a 5-4-1 formation and they become so polymorphic in attack with 3-5-2 by pushing forward on the left or right full backs to the middle field and 2 middle filed players will be come Supportive Strikers or forwards. The team get their tactics right and is not a surprise for me to see them qualifying on the 16 of the world cup. There is talent for sure but in my opinion, there is more team work and tactics.
Greeks have the experience and the ability to knock out Costa Rica but the question is...... Will Mr Santos realize that 2 middle field players (Karagounis who is not marking at all) will not be enough against 4-6 middle field Costa Rica players? Will he realize that with Karagounis and Salpingdtidis  in the first 11 team is putting in a risk the whole defensive operation of the team and the central Latin Americans will put so much pressure to the Greek defence? My First eleven for today would be: 
Greece (Possible, 4-1-2-1-2): Karnezis; Torosidis, Manolas, Papasthathopoulos, Tzavellas; Holebas, Samaris, Karagounis; Maniatis, Christodoulopoulos , Samaras. 

If the Greeks will not fall into the Costa Rican's trap like the Italians did, then they will qualify for first time in their history to the Quarter Finals of the World Cup. 
In terms of betting I agree with the bookies that this could be an Under 2,5 goals game however the value does not worth the 'risk'. The 0-0 score offers price not more higher than 7.00 (6/1) and the Under 2.5 goals is no even touching the price of 1.50 I will go to scores 1-1 and 0-1 for Greece where the prices are more descent.

In the the other game today, I think that Netherlands might be 'betrayed' by their defence..... It happened so many times in the past. Both teams to score and scores 1-2 for Mexico or 1-1.

Pirates of the dream are called the Greeks and they intend to make it happen. 
No doubt that Greeks have a rare opportunity to go through to next round. Long time ago, I expressed my doubts about the philosophy of the coach Fernando Santos regarding to his tactics. In my opinion, depending on the qualities of the players and their temperament and form, the appropriate tactics and players should be used. 
To be more specific, I have always believed that formation 4-3-2-1 is absolutely wrong for the Greeks. Specially when Mr Santos trusts the position of number 6 to player Katsouranis (middle field defensive player). No doubt he is a great player but he is in a very poor condition. Moving on to the choices of Salpingtidis and Gekas, what can I say....... I am speechless. These players again are in a poor condition and with Samaras wasted on the left wing, the Greeks are no threat and there is no player to create in the middle field.  I was surprised to see  during the game of Colombia Mr Santos to substitute the Gekas and Salpingtidis and he kept them out of the squad also against the team of Japan.  What about Katsouranis? Once again he trusted him with the position of  number 6 and we have been awarded with poor performance and a red card. Is it coincidence that after the red card of Katsouranis the team played better? I don't think so..... 
Greeks can play the game they know to play better. We do not have powerful middle field line to trust 3 middle field players but what we do have are powerful wingers and central forwards. 
My first 11 for today would be: Goalkeeper Kapino, Left back defender Tzavelas, centre defenders Manolas and Papastathopoulos, right back defender Torosidis, Defensive middle field players Maniatis and Kone a bit forward, Left winger Holebas, right wing Fetfatzidis. I would give to Samaras a ''free role'' of Supportive Striker and Forward Mitroglou. 4-4-1-1 the formation I would pick today. 
I hope to be wrong, because if Karagounis and Salpingidis start the game, it will not turn out well.  
Both teams to score is my prediction with scores 1-1 or 2-1 for Greece. Best of luck and let's hope that Mr Santos, will not blow up the game again.
