Lewandowski isn't Schürrle and vice versa. I've watched a lot of Schürrles games, actually, and he was getting pushed off the ball too often for my liking to be called "strong". Btw, blame it on the guy who invented that term. As I already said above, judging from the games he's given me the impression that he lacks the strenght to hold its own at times. And again, Schürrle is not Lewandowski or whatsoever. Might as well bring up that Boateng physically overrun Lewandowski completely, and that (considering that Boateng is one of the worst defenders at making use of body strenght in tackles) is worrying, isn't it? Btw, are you the same person or brothers or friends or lovers or whatever?!
