Except that isnt the role required on the outside. Podolski is quick, creates well, tracks back hard. There is a reason he is always there. He is the second forward in the side. Playmaker through the middle, hard working winger forward on the right, its pretty much how Germany always line up. Gotze is a 10, and his place is occupied by Ozil.
He can play on the flanks though, maybe even give him a try instead of Muller then. I seriously think he would be a huge threat to any defence and he is far too good to be left on the bench.
