Greece’s preparation for their upcoming last 16 battle against Costa Rica is not going smoothly as injury issues troubling some of their players, notably Etnhiki’s talisman, Georgios Samaras.

Samaras’ fitness is reportedly in doubt after missing out from Greece’s latest training session, spreading fear among their fans as the match against Costa Rica is very near.

Aside from the Celtic attacker, another injury problem is also hampering midfielder, Panagiotis Kone who only managed to do some light jogging on that latest training session.

Both Greece and Costa Rica arrived as an unexpected teams from their group and now one of them could write more sweet history by advancing into the Quarter finals of World Cup 2014.
