The Munich-born midfielder is no stranger to big cities after his time in Stuttgart and Rome. It is not the bright lights that has attracted him, however.
Hitzlsperger told whufc.com: "London is a great city but my decision was solely about the club. I am going to West Ham to be successful as a footballer. You have to do your job right and then you can enjoy everything else. I am here to work and do my best.
"Stuttgart was a great experience but I am glad to be going back to the Premier League [after playing for Aston Villa between 2000 and 2005]. My experience in Italy wasn't great but it will help make me stronger for this new challenge."
Since news of his move emerged, Hitzlsperger revealed he had been approached by many German fans wanting to discuss his new club.
"West Ham are well known in Germany. Since the news broke a lot of people have been talking about the club and the history.
"I have spoken to people who know TSV 1860 Munich and I know there is a connection there between the two clubs. West Ham have a great history, but it would be nice to write a new chapter and have success.
"I saw them a bit last season and they were unfortunate. I think the only player I know personally is Carlton Cole, who had a year at Villa. You could see what a talent he was and on his day he can be as good as anyone. He is a good lad and I am looking forward to seeing him again and meeting everyone.
"I am really motivated to do well. I like the claret and blue colours very much and it will be great to pull on the West Ham shirt. I also remember the stadium as well. They tell me it is special at night and I can't wait to experience that."
