Lazaros has been one of our best players for a year now. I, too, don't get the hate for him. He is an automatic call-up for me at this point. Certainly been more consistent than Kone.
As for Vellidis, Stafylidis, Tasoulis, Fountas, and Kolovos...if we have no GKs, then it makes sense to get Vellidis there as soon as possible. Stafylidis is a no brainer, and since he's available to train with the team, then it would be silly to not have him there already training. Can't really speak for the other two, although as NT coach, you'd assume Markarian is going to try out his fair share of players as he decides what he wants the team to look like. If the reports are correct, then I am pleased he has players with him this far out from the match.
