At the risk of repeating myself (though what's written on the FIFA forums doesn't count anymore, hehe... ) but I truly think that prolific, clinical finishers such as Robert Lewandowski and Harry Kane are overrated as football players. Great strikers, but not the hanger you'd hang the rest of your outfit on. As much as Lewandowski tries he can never take Poland far, in a way that Messi can with Argentina or Ronaldo has done with Portugal. And the same goes for Harry Kane: a striker is as good as the supply he gets.
And Bayern always have a relatively conservative start to their seasons. Second half of the season, it will go as smooth as a rodant's treadmill and they'll add another title, you'll see.
