Defensive midfielder Polanski, 25, who has been picked for the 10 August home friendly against Georgia, plays for Bundesliga side Mainz and was born in 1986 in Silesia, southern Poland's industrial hub which is home to a large ethnic-German minority. His family emigrated when he was three years old.
Polanski's career started at Borussia Monchengladbach. He spent the 2008/9 season with Spain's Getafe, before signing to Mainz. He also captained Germany's U-21, and featured 19 times, but has not featured in the senior side - something commentators have said may have made up his mind when Poland came calling. Polanski holds Polish citizenship having been born in the country.
Smuda's squad also includes French-born midfielder Ludovic Obraniak, whose grandparents were Polish emigrants, making him eligible for citizenship without living here. Now 26, he was first capped by Poland in 2009. He has worn the red and white shirt 16 times, and scored four goals.
