Muller said that he was deployed more centrally for Bayern to take control of the midfield, which led to City's forward men being isolated on the night.
"Through that [change of role] we wanted to gain superiority in midfield," Muller told Kicker. "I am not the kind of player who waits to get the ball in one-on-one situations with the defender, but rather the guy that drops deep or tries to come through over the wing - and who also helps his team defensively.
"Manchester had two attackers who - and I exaggerate a bit - sat in their deckchairs on the halfway line when we were in possession. No attacker is allowed to do that at Bayern or the Germany team."
Muller has 16 goals in 44 appearances for Germany.
