I agree actually but the national team has been having fullbacks after the 2004 era who were mediocre at best defensively.
Holebas was like Koutris in his youth, offensively too good but mediocre defensively AT BEST. This is exactly the reason why IMHO putting a 3rd CB could be able to unlcok our fullbacks full potential. They have the lungs to track back when needed and they ll have the free choice to move forward and cross or man to man which unironically Koutris is too good at.
Our NT's biggest problem is actually the transition. Getting the ball forward quickly. These guys are good offensively and they can definately help with that. It's gonna be like we have 2 extra midfielders on the wings and 2 more options for Fortounis to pass to and not have to go back to take the ball and carry it himself.
However, the biggest issue we have to hope is that at least one or two of the guys we have on the wings actually make a career we hope them to make , Lamprou, Limnios, Chatzigiovanis, Bouzoukis. I would be quite devastated if they all ended up Greek Super League flops. Even Koulouris and Donis, we should hope they dont get suddently lost to mediocricy.
I believe there is actually a lot of talent which if managed properly (Managers guiding them for a good career and not for some extra cash in their pockets and coaches properly teaching them how to play the damn ball) I can see us back on track with our previous success decade, where we barely missed any major tournament.
