Behrami became the first Swiss to play at four World Cups last year. Days after a round of 16 loss to Sweden, he married Swiss Alpine ski star Lara Gut. The 34-year-old Behrami returns to the national league he left as a teenager in 2003.
He played briefly for Lugano before moving to Italy, England, and Germany, including with Lazio, Napoli, West Ham and Hamburger SV. He was a free agent after a two-year spell with Udinese. Sion opens the Swiss league hosting Basel on July 19.
