Neustadter gets Russian passport ahead of Euro 2016
Russian President Vladimir Putin signed a decree last Wednesday to grant citizenship to the 28-year-old, who will now play for Russia at the upcoming UEFA European Championships in France.
The Schalke 04 defender was born in Dnipropetrovsk, Ukraine, but moved to Germany in the early 1990s.
His father, Pyotr Neustadter, enjoyed a long playing career in Russia and Germany, before taking up managerial roles with FSV Mainz 05 II and TuS Koblenz.
Neustadter junior played for Mainz and Borussia Monchengladbach before switching to Schalke in 2012.
He has established himself as a permanent fixture in the first team, helping the club to fifth in the table last season and a place in the Europa League next term.
Neustadter previously played twice for the German national team in non-competitive games, leaving him clear to play for Russia.
Another new citizen in the Russian Euro 2016 squad is goalkeeper Marinato Guilherme.
The Brazilian-born stopper received citizenship last November and made his Russian debut in a friendly against Lithuania in March.
Russia face England in their opening game of Euro 2016 in Marseille on June 11, before meeting Slovakia four days later.
They round off their Group B fixtures against Wales on June 20.
