He cut in centrally a lot during his time at leftback, but was an out and out rightback from 2009 -2013 with the short exception when injuries forced him back to the left for a while in Heynckes' first season. Lahm's best season was the treble winning year and he mostly played behind Müller who was more a free roaming 2nd forward than a winger and Lahm provided all the width on his own. Only late in that season Robben came back into the first team when Kroos got injured.He was still used centrally long before Pep. I'd rate his best attacking season while LvG was in charge and he played as right back behind Robben. Not exactly wing back with one of the best right wingers nowadays.
In general he played almost as much time behind Müller than he did behind Robben because of the latter's injury record and there rarely was a lack of width in the team no matter how much time Müller spent centrally. And he didn't have a player like Neeskens helping him like he has in this game.
