Portugal have won two games out of two in the UEFA Nations League so far and will look to make it three when they face Poland away on Saturday.
Roberto Martinez's side claimed victories over Croatia and Scotland in September, while the Poles beat Scotland and suffered defeat against Croatia.
Here's how the two squads are shaping up heading into this one.

Wojciech Szczesny retired from international football after the Euros so isn't involved. He actually initially retired from football altogether before an SOS came from Barcelona following an injury to Marc-Andre ter Stegen.
Stalwart Robert Lewandowski is involved and comes into the international break in fine form for Barcelona.
Mateusz Bogusz and Bartosz Slisz were not called up.
There have been no fresh pullouts or injury concerns since the squad announcement from head coach Michal Probierz.

Poland vs Portugal Expected Lineups
There will definitely be alterations in the final third from both managers from the last game, as Bogusz has not been called up even though he started against Croatia. Krzysztof Piatek could therefore be the man to partner Lewandowski.
As for Portugal, Ronaldo didn't start the last one yet came off the bench to score against Scotland so he is a definite starter.
Poland (5-3-2): Skorupski; Kaminski, Walukiewicz, Bednarek, Dawidowicz, Zalewski; Szymanski, Zielinski, Urbanski; Piatek, Lewandowski
Portugal (4-3-3): Costa; Semedo, Dias, A. Silva, Mendes: Vitinha, Palhinha, B. Fernandes; B. Silva, Ronaldo, Leao
