Karnezis, Sokratis, K.Papadopoulos, Manolas, Samaris, Holebas and Torosidis should be the players that start every match coming up. Thats our defence. The rest need to be changes often. For eg. have Ninis or Fortounis to start in that creative AM role. Maybe Pelkas aswell. Striker next game would have to be either Klaus or Aravidis, Mitroglou has to sit on the bench. He can come on if the new striker is not producing anything. Have 1 of Kone or Lazaros to start on that LW. RW should be Fetfatzidis. Tachtsidis can be on the bench as well as Karelis. Kapino and Vellidis as keepers and Maniatis to be a back up for Torosidis for now. Have 3 future players that were going to fit in for later to gain knowledge of how we play for eg. (Bouchalakis, Pelkas and Petsos.) I like to see Bakakis in the future because i think he is talented. Aswell as Mystakidis. Mystakidis is like Kone in the way his position is second striker. They both like to roam around the box. Stafylidis should be back up to Holebas and Siovas, Oikonmou should be back ups.
Overall this is what i would do if i was coach. I would be tossing up between Fetfatzidis and Karelis in that RW position of who should start most of the time. I also think that 1 of Lazaros and Kone should start on that LW. As Samaras has no club. This Squad is young and filled with a core of expirienced players (meaning caps.) Tziolis should step aside not because he's old but give the new generation a chance in that position such as Bouchalakis, Petsos and Lagos. We need to give these players playing time and become a team. Maybe have Tziolis there if it means to have balance so the team will not be lost.
