I do agree that his "curse" is more than a joke now and I feel like him not winning is quite funny (to us of course, not to him) but we can't blame him for that, he did all he could and he tried his very best, he scored way more than what we expected of him to score. If he scored a bit more he almost broke over the Bundesliga record that Lewandwoski has, so that means that whatever Bayern Munich had trouble this season long, it was not his mistake and he didn't cause any of it, he did what he should and rest of the team basically failed him at the end so he wasn't responsible for their loss.
I think it is even easier for him to score goals in the Bundesliga compared to the Premier League. This has also helped him score this many and he can go for even more in the remaining games.
He has always been playing really impressively. He has won many individual prizes many of which were top scorer ones. Despite his giving his best every season he is just unlucky with titles. But like I said before I think there is no way he isn't breaking a leg at Bayern Munich. Yeah Leverkusen are really solid with Xabi Alonso but one way or another Bayern Munich would start winning titles once again. It can happen next season too if they bring the right manager for themselves.
