The former Luzern prospect is beginning to impress in Germany and has drawn comparisons with Shaqiri.
Asked about the Reds star, Vargas admits he hopes to line up alongside him for Switzerland.
"Everyone knows Xherdan Shaqiri. I've always followed him too. Every young player dreams of such a career," he told Blick.
"I can still learn a lot from him. I hope to play with him in Nati soon. So far this has not happened."
