"Dortmund and Bayern are the only clubs I've played for, but Bayern are one of the best three teams in the world and have the chance to win everything every year," the Germany international defender told the assembled press at his official unveiling as a Bayern player on Saturday. "In the end, that was the decisive factor."

The fact Hummels already knew his way around the Bavarian capital, having come up through the Bayern youth ranks, also played its part. "I've known a lot of people around here for a number of years," the 27-year-old explained. "A lot of my friends live in Munich too. I'll have no problems settling in."

Official Bundesliga Fantasy: top 10 defenders

As fate would have it, a Supercup meeting with former club Dortmund is first on the competitive agenda for Hummels at the SIGNAL IDUNA PARK on 14 August. Even though he was the bedrock of the side that won back-to-back Bundesliga titles in 2010/11 and 2011/12, the World Cup winner acknowledges that some fans will never be able to accept his departure.

"The boos from the Dortmund supporters will come, but even if they're still there after 15 games in a row it won't change how I feel [about them and the club]" he said. "The decision to move gave me a real headache for a number of weeks - it was a long and difficult process. I can't speak for everyone, but the Supercup will be a really special game for me. We'll have to see if I start."
