The former Switzerland Under-21s international is a new face at the Stadium of Light, having signed a three-year deal along with Valentin Roberge and Modibo Diakite on Monday.
The 24-year-old believes this latest chapter in his career will provide his greatest challenge, despite having won five league titles with previous club Basel, and highlighted his happiness at playing in front of the Black Cats fans.

"I am playing for Sunderland in England; I am happy. In Basel there are passionate fans – around 20,000 or so per game – but this different. Every game we play, the fans are always there and that is important for the team. In the game, I battle for the fans."
The midfielder hopes to use his experience in European competitions to his advantage and admits that the presence of manager Paolo Di Canio was an attraction.
"The Champions League was very good and a great experience for the young players," he remarked of his exploits with Basel. "Last year we played in the Europa League and for a Swiss club to reach the semi-finals was very good also.
"[Di Canio] is outstanding. First he was a big player, now a great coach. He gives everything for the team. I like the coach. He is passionate and always wanting the team to do better."
