Åenol GüneÅ’ side have been poor so far and were thoroughly outplayed by Wales last time out.
While Vladimir PetkoviÄ’s side have not been much better and took a beating at the hands of Italy last time out. Though they did show glimpses of potential early on against Wales to secure a point, meaning they have the edge here and victory will likely help them to advance to the last 16.
With Italy already through and Wales on the brink of joining them, the burden is on these sides to force it and claim all three points, potentially by more than one goal to boost their goal difference and boost their hopes of advancing.

What is the team news?
Both sides have full squads to select their lineups from, with Switzerland likely to swap out their forwards, with Haris Seferovic not impressing last time out and Mario Gavranovic providing bright moments late on against the Azzurri.
Djibril Sow, or Denis Zakaria, could freshen things up in the midfield alongside Granit Xhaka, with Remo Freuler possibly dropping out.
As for Turkey, the first issue will be who partners Caglar Soyuncu, with Merih Demiral primed to return to the starting lineup with Kaan Ayhan preferred against Wales.
Yusuf YazÄ±cÄ± will likely battle it out with Ozan Tufan to complete the midfield trident, with Hakan Calhanoglu likely to be deployed in midfield to better link Turkey’s build-up play.
Cengiz Under was bright last time out and should flank Burak Yilmaz, while Ibrahim Halil Dervisoglu, who has replaced Kenan Karaman in both games off the bench, could push for a start here.
Switzerland XI: Yann Sommer, Nico Elvedi, Fabian Schar, Manuel Akanji, Kevin Mbabu, Djibril Sow, Granit Xhaka, Ricardo Rodriguez, Xherdan Shaqiri, Mario Gavranovic, Breel Embolo
Turkey XI: Ugurcan Cakir, Mert Muldur, Merih Demiral, Caglar Soyuncu, Cengiz MeraÅ, Okay Yokuslu, Cengiz Under, Hakan Calhanoglu, Yusuf Yazici, Kenan Karaman; Burak Yilmaz
Switzerland - 4/6
Draw - 29/10
Turkey - 4/1
Turkey have been among the biggest disappointments of the tournament so far and after two dreadful performances, they will surely respond here, naturally the Swiss took a heavy beating from the Italians too, last time out, so the motivation for both to take some risks is there. So, rather optimistically we’re going for some goals here, and a Swiss victory, 3-1, which should be enough to take them through.
