Aside of the fact that there's no real RB in your squad we might be better if we use 3 in the back, something like Siovas/Manolas/Mavropanos with Tsimikas and Limnios being the full backs. In the midfield I'd like Bouchalakis and Galanopoulos with Fortounis in front of them, then Donis and Pavlidis up front. I'd take Stafylidis out because he's out of form for more than a year and we literally don't need 4 Left backs in the squad. Lykogiannis of Calgiari would be a much better alternative.
