He told Newcastle's website: "I'm really happy to be at this amazing club. From the first contact, I felt like the club really wanted me and had big plans for me. It's a big step in my life to leave Germany but everybody has welcomed me so well and it already feels like family. I have a really good feeling from speaking to the head coach that this is the right place for me to find my best level. I know the stadium from watching games on television - it looks amazing and I know the atmosphere is crazy. I'm really excited to play and start scoring goals here."
