But it is the "old" guys that are doing the show. Müller is on 6 goals and 7 assists in the 6 and a half matches he played, Ribery has really been great in the last 3 or 4 matches, Kroos, Gustavo and Schweinsteiger each have 3 goals. Yes, Mandzukic is great with his 7 goals until now, too - and Dante is a great defender. Shaqiri has shown that he is somebody that really can make power again when you change him in and his set pieces are great. And Martinez still needs time and will get it - we hopefully need him at the end of the season.
I think a lot of the old Bayern players got some well needed motivational boost through the fact that now there are even more quality players competing for their place in the team.
Since Bayern bought Martinez, Luis Gustavo practically exploded playing on a level for Bayern he never has played before.
Same seems to be the case for Kroos, Schweinstiger, Ribery and Müller.
Alaba being back in the team will only further increase the competition for a starting spot in defense as well.
They have a quality team and an incredible squad depth atm, it will be hard for any team in the world to beat them this season, if they stay focused.
