Rojas needs a fresh start and Thun could be a good place to do it. The club, based 30km south of Berne, was founded more than 100 years ago. Thun has moved between divisions across its history but been established in the top flight since 2002, apart from a one year stint in the second tier Challenge League in the 2008-09 season.
Thun qualified for the UEFA Champions League in the 2005-06 season and were a few minutes away from a famous draw against Arsenal in London, before a late Denis Bergkamp goal. The club has also qualified for the Europa League in two of the past three seasons.
There had been talk of Rojas returning to the A League but the former Phoenix and Melbourne Victory player still has European ambitions.
"Just because it has taken a little while to get going doesn't mean I am going to give up on my dream," said Rojas. "As a youngster I always wanted to play in Europe. I still want to make it in Europe and I believe I can."
Wynton Rufer is New Zealand's most famous footballing export to Switzerland, scoring almost 100 goals in a seven year stint in the 1980s. Brother Shane Rufer also played in the Central European country.
