Prognosis for Greece vs Costa Rica

costa rica has every obligation to win but this greece team has a lot of heart and has no shame playing with 10 men behind the ball for 80 % of the game. i think a coin toss would be the most accurate way to call that game .  Costa Rica showed a lot of heart and speed and some very interesting individual talent in two of their players.  They also have an excellent keeper.
I don't think Costa Rica have ever faced a team like Greece.  Greece is arguably the worst team in terms of technical ability in the world cup.  But the have heart.  Lots of it.  And a very seasoned, experienced coach at both the club and international level.  Greece is not ashamed to play 10 men behind the ball for most of the game.  They don't claim they will play pretty football.  They are efficient.  They also have a few interesting role players.  Karagounis is old and can't play 90 minutes anymore but he can still show flashes of his old playmaking skills.  He is also not afraid to have a shot from 30 yards out. 
Mitroglou is a solid striker but has been struggling with health issues and we don't even know if he will play.  But this Greece side promised to play a very compact and disciplined defensive game waiting for their opportunities for rapid counter attacks led mainly by samaras on the wing.  So while Costa Rica does have some good weapons and speed on the wing, its nothing Greece hasn't seen before playing in Europe and qualifying from there.  They have many many times shut down and defeated teams that are much better than them.
So very hard to make a call either way.  Costa Rica is a superior team with far superior technical ability.  They also have few players experienced in the top elite competition of european club football.  Best way to call this game is with a coin toss.
