good news is that core of this team is still young. In 2014, Hološko and Kopunek shall turn 30, Skrtel, Salata (I also add Guede) shall be 29, Kucka 28, Hamsik, Pekarik and Jendrišek 27, Stoch and Weiss 24. Plus a lot of promising youngsters probably make it into the squad meantime, like Kubik (25), Mak (23), Lalkovič (21), Gregus (24) etc.
Also, Durica, Vittek and Sapara shall be 32, Šesták 31, they can add veteran experience.
Only missing vets from 2010 squad shall be Karhan, Kozak (useless anyway) and Strba, and probably Zabavnik.
Karhan and Strba shall have adequate replacement in Kucka, Guede Kopunek or Gregus. Zabavnik is replacable by one of LukšĂk or Hanzel.
