It's tough to keep good players if teams from the top-5 leagues show interest. If Lazio want Kace we have zero chance and it's hard to argue. Arnesen valued him at E4 mill earlier this year so I say deal him! If we are being 100% honest, I don't think he gets much better. He is at or near his ceiling. Undersized for his position and not a great north-south passer nor does he have particularly good field vision. His strengths are set pieces, his motor, and the ability to cut passing lanes. Those can be replaced.

I agree that Cimirot is a "better" player, but he is more creator and less defender. The ability to see open spaces, hold and advance the ball upfield are way tougher to find than what Kace brings. He needs to play.
Tziolis > Sabo and arguably our most "important" player this season. I think a Tziolis-Charisis-Cimirot/Pelkas midfield trio is our best option. Pelkas has gotten praise from Berba, Tudor, Arnesen and Pacienca at Setubal. He has talent but lacks consistency. He is young with <50 games of top flight football. Patience is important, admittedly a trait not found in our DNA as PAOK fans.
