A draw with Czech Republic would be enough to join Portugal in the last 16, so the Crescent-Stars can choose to play on the counter if they wish - perhaps influencing their team selection.
Vincenzo Montella's men were handed a chastening 3-0 defeat last time out, and the Italian coach must make at least one change to the side that lined up against Portugal in Dortmund, due to Abdulkerim Bardakci's suspension.
Having being booked twice in two games, the Galatasaray defender must serve a one-match ban, so either Merih Demiral or Mert Muldur will have to deputise - the latter is also a contender to replace Zeki Celik at right-back.
After being unable to start rising star Arda Guler at the weekend, due to a groin injury sustained in training, Montella may now select the Real Madrid forward alongside fellow teenager Kenan Yildiz, of Juventus.
With Irfan Can Kahveci also available, the Italian coach can now choose from a deeper pool of resources, but the versatile Baris Alper Yilmaz is expected to retain his place up front.
First-choice goalkeeper Mert Gunok has missed more training sessions because of a knee injury, so Manchester United reserve Altay Bayindir may keep the gloves despite playing his part in an awful own goal against Portugal.
Turkey possible starting lineup: Bayindir; Muldur, Demiral, Ayhan, Kadioglu; Yuksek, Calhanoglu; Akturkoglu, Guler, Yildiz; Yilmaz
