Completely unrelated. Machado is a central midfielder, signed today by olympiakos after months of flirting - money was already set aside for him i believe. He will sit in the middle and help Maniatis. Olympiakos on ground level will be shocked if this happens as the only obvious replacement will be Fetfatzidis who coaches seem to be afraid to play or the even younger Vlachodimos. However as you alluded to Marinakis, the boss, is the one who makes these decisions and if he gives the OK, the rest will be written in stone.
