The 29-year-old came through the ranks of the Bayern youth academy, but left the club for Duisburg after failing to secure regular first-team action at the Allianz Arena.
He then played for Werder Bremen, Kaiserslautern, Hertha Berlin and Darmstadt, before joining Hoffenheim ahead of the 2016-17 campaign.
Wagner has quickly become a key figure at the Rhein-Neckar-Arena and he is now hoping to earn a move back to his boyhood club.
“Bayern are my club and will always be my club,” the striker told Bild.
“That is why I can very well imagine myself returning to Bayern at some point.
“But I do not know whether I will return as a player or in another position.”
Wagner has made it clear Bayern are not the only club on his mind, though, as a move to the Premier League would also be an option.
“I have had offers in the past and I am still receiving offers. I am happy with the interest being shown in me,” he added.
“That is recognition for what I am doing on the pitch. And I cannot rule out a move to the Premier League at some point.”
