I feel like we always have better options on the bench. Look what happened with Misic and Ingassen. Those two are clearly better than who was being played ahead of them. I think Zivkovic and Pascha are pretty much the same talent level, Pascha takes more risks which hurts him but I would say he is more athletic and stronger than Zivko. I wonder how Rodrigo is at RB, Matos, for me, is having a rough season so I wouldn't be surprised if Rodrigo gets a shot if we end up liking him more.
Rey is an interesting case, I always liked him. He never caused trouble when he wasn't playing and seemed like a great teammate who loved being in Greece. I would say he is on the same level as Zivko. He is a technical GK, great footwork, positioning, communication, but isnt at the same athletic level as Pascha.
