JeanMarc, are you sure about main position for second set? Aachen usually played in a 2-3-5 at that time, with Zebec as center-half

One example from a match against Schwarz-Weiss Essen in 1962:
-------------------Prokop-------------------------
---------------Krisp-----Nievelstein--------------
------Martinelli----Zebec------Breuer-----------
-----------Glenski-------Laumann---------------
------Esser------Bergstein------Broichhausen--
After Martinelli was used as CF in the following seasons, Thelen used to play alongside Zebec and Breuer:
Alemannia Aachen - Arminia Bielefeld (26/04/1964)
-------------------Prokop-------------------------
---------------Krisp-----Nievelstein--------------
--------Thelen----Zebec------Breuer-----------
-----------Glenski--------Hahn------------------
------Esser-----Martinelli-----Gronen-----------
Position could be changed but the choice is up to you
