Renato Sanches has been handed a starting role for Portugal Under-21s' meeting with Spain Under-21s after being overlooked last time out.
The Bayern Munich midfielder was a surprise omission for the 2-0 win over Serbia in the Selecao's U21 Euro 2017 opener, but after coming off the bench to set up the second goal he is reinstated for this Iberian derby in Gdynia.
Sanches's inclusion means that Diogo Jota drops out, as boss Rui Jorge alters his formation and instead goes with a two-man frontline - Goncalo Guedes and Daniel Podence starting just ahead of the Bayern man.
Albert Celades has made two changes to Spain's starting lineup, meanwhile, bringing in Jonny and Dani Ceballos for Jose Luis Gaya and Denis Suarez.
La Rojita won their opening game 5-0 against Macedonia, putting them in a strong position in the early Group B standings, with only the top side guaranteed a passage through to the semis.
Portugal Under-21s: Varela; Cancelo, Ie, Ruben Semedo, Rodrigues; Carvalho, Neves, Fernandes; Sanches, Podence; Guedes
Spain Under-21s: Kepa; Bellerin, Vallejo, Mere, Jonny; Llorente, Niguez; Asensio, Ceballos, Deulofeu; Sandro
