I thought Petsos had a really good game against Montenegaro and has good upside. I Can't really comment on his speed and mobility, because he hasn't featured since. Regardless, wether we like it or not, the Samaris-Maniatis combo appears to be the most effective and what we will see for the next little while, however their club status' may become an issue going forward in this campaign. I have no issues inserting Maniatis if he provides better coverage for toro, but Petsos' technical ability appeared superior.
If they play regularly at club level, Cholevas and Toro should be able to fill these roles sufficiently for the next couple of years, we rely on them getting forward regardless, with the 3 CM/2 DM combo hopefully relieving them of some of their defensive duties. This formation is better suited for Stafy as well, with Tzavellas to the bench as both would be exposed by in a flat back line. if Tzavellas continues to feature in this campaign, we will undoubtedly get scored on when he raises his hand for a non offside call, flops to the ground for a non existent foul or when he bites on shot fake.
