Yes yes, I get what Sheriff is saying also. But, what can we seriously expect from a team that hasn't kept a manager for longer than 8 months in the last 4 seasons ? Note that our fans don't help either.
As for expecting players that are leaders or can make the difference, how can a team like PAOK attract such players ? The answer is they can't easily. A player that is that easy to spot, will have been poached by a better club in a better league long before a team like PAOK can get them. All PAOK can do is to try and acquire players that show glimmers of something, and hope that given the chance they will reach some sort of hypothetical potential. Sometimes it will works e.g. Lucas, Mak, sometimes it won't. PAOK doesn't currently have the mentality as a club or the funds to be able to just "make" a team that can regularly and consistently put teams like Ajax way.
There are a core of players currently in the team that are semi-solid players like Tzavellas, Leovac, Charisis, Cimirot, Kace, Pelkas, Mystakidis, Rodrigues, Pereyra that are all decent players on their day. The hard part is having them all fit and in form at the same time. I am hoping that some of the new transfers like Matos, Shakhov, Canas, Biseswar, Djalma will be another small step up in "kwality" as Tudor used to say.
Having said all that, I've always thought that the most logical expectation one should have for their team, is that it is better and improving from one season to the next. With that in mind I am quietly optimistic about this seasons transfers. Will PAOK beat Ajax ? I don't know. But I will be disappointed if the team this season is not better than last season. And yes, Mak will be sorely missed.
