The Crescent-Stars suffered a disappointing 3-0 loss to tournament co-hosts Italy in their opening match last Friday.
Turkey had just three shots in that game - their fewest ever in a European Championship match, failing to register a single attempt on target in the second half.
A slight tweak in formation that could see Hakan Calhanoglu move into a more central position is a possibility against Wales.
Up top, Burak Yilmaz - who scored 16 goals in 28 Ligue 1 appearances for shock champions Lille last season - should get the nod as the focal point of the side.
Turkey possible starting lineup: Cakir; Celik, Demiral, Soyuncu, Meras; Under, Yazici, Yokuslu, Kahveci, Calhanoglu; Yilmaz
