Olympiacos Piraeus is currently deep in its summer training program, which recently included a friendly match against Royal Antwerp in Belgium, ending in a 3-0 defeat for the Greek side. Despite the loss, manager José Luis Mendilibar utilized the match at Bosuil Stadium to assess team performance ahead of the upcoming qualification match against NEC Nijmegen, scheduled for August 4th at the Georgios Karaiskakis Stadium. The Piraeus team had previously played other friendlies against Raków, Leuven, Fortuna Sittard, and Ajax.

In a parallel development, a separate team managed by Giorgos Kostis is also in its preparation phase. Following a 0-3 loss against APOEL, this squad is focusing on squad integration and testing new personnel. Kostis is looking to strengthen the roster in key attacking positions to ensure depth and balance. As part of this ongoing evaluation, the team is scheduled to face AEL in a friendly match at the opponent's training center, with further rotations expected to determine the squad's competitive readiness.
