- Fabrice-Jean Picault, Caleb Stanko and Zack Steffen earn debut call-ups.

- USA face Puerto Rico on 22 May ahead of Copa America, which kicks off in California on 3 June.

Jürgen Klinsmann has named eight Germany-based players in a transitional squad for next week’s friendly against Puerto Rico ahead of the Copa America Centenario in June.

The list includes four players from Bundesliga 2, about whom you may not know too much. Allow to fill you in…

Bobby Wood

Wood has had a 2016 to remember so far. He scored in all eight Bundesliga 2 appearances since the turn of the year – hitting ten goals in that spell – and his season tally of 17 is the most scored by any American player to have played in the Bundesliga or Bundesliga 2.Considering he had scored six goals in two years in the second tier before the campaign began, his improvement is remarkable. You can watch his record-breaking goal against SC Paderborn 07 on Matchday 29 below.

Fabrice-Jean Picault

"Fafa" Picault scored both goals in FC St. Pauli’s 2-0 win over VfL Bochum on Matchday 30, taking the Man of the Match award. He finished the season with four goals and an assist to help Pauli finish fourth.
