Stan Wawrinka breezed past Andreas Seppi in the fourth round of the Australian Open, and his play was so formidable that a fan confused him for Roger Federer. Wawrinka was quick to correct him, saying, "Not here, he's on Rod Laver."

Both Federer and Wawrinka are safely through to the quarterfinals with Wawrinka winning in straight sets and Federer battling in five against Kei Nishikori.

The two top Swiss stars could potentially face off in the semifinals.
