The 28 year-old made the announcement yesterday and admits a move to England does interest him. Aston Villa and West Brom have been linked with Wagner this season.
"I'm at a good old age, have played a good season and will now just see what the options are. Yesterday we again had a final conversation and they have said that they will lay no obstacles in the way," he said.
"I'm going in the next few days on vacation and to think about what I want.
"England or Germany, both are interesting."
