'With Heynckes in 2013 , in the big games we played quite defensive on the counter attack . Everybody worked together as a group , we invested a lot of energy in the games , ' Lahm said . 'Now under Pep it 's more tactical and we have more possession but not like previously when we had a lot of possession but we did n't have any clear scoring opportunities .

I 'm born in Munich , I grew up here , I 've been at Bayern Munich since I was 12 years old besides the two years in Stuttgart .
