Kitsiou I rated a long time ago. Bakakis and Lykogiannis need to be tried. Koutris has a future. We have leftbacks we also have some right backs. By the biggest issue and the reason why this topic is here is that we will probably not have a decent enough replacement for Mitroglou.
Old strikers such as Charisteas, Gekas, Vryzas, Nikolaidis and Salpingidis are all legends and have retired. Now we have Karelis who is injury prone and Donis who is currently injured. I believe in the future we will have midfielders than can pass a ball unlike Tziolis and have more of a brain unlike Samaris and Tziolis.
Samaras was very good in that sole striker position. Mitroglou is very slow. I know he is a target man but with our current midfield like Samaris, Tachtisidis and Tziolis where will the goals come from. These midfielders mentioned play very one dimensional at times and with a static striker like Mitroglou it's very easy for opposing defenders to close down. We need to fix this problem as we will not score and therefore not be in major tournaments. The full back position is the least of our problems.
