Teenage midfielder Xherdan Shaqiri was a surprise selection in Switzerland's 23-man squad for the World Cup on Tuesday.
The 18-year-old Shaqiri made his club debut for FC Basel last July, and has played just 45 minutes of international football, in a friendly against Uruguay.
Switzerland coach Ottmar Hitzfeld selected Philippe Senderos despite the defender being largely out of favor this season at Arsenal and on loan to Everton.
Hitzfeld retained nine of the players taken by predecessor Koebi Kuhn to the 2006 World Cup in Germany, where the Swiss reached the round of 16.
Switzerland is in Group H and plays tournament favorite Spain on June 16, Chile on June 21 and Honduras on June 25.
Swiss provisional squad:
Goalkeepers: Diego Benaglio (Wolfsburg), Johnny Leoni (Zurich), Marco Woelfli (Young Boys).
Defenders: Stephan Lichtsteiner (Lazio), Stephane Grichting (Auxerre), Steve Von Bergen (Hertha Berlin), Philippe Senderos (Arsenal), Mario Eggimann (Hannover), Christoph Spycher (Eintracht Frankfurt), Reto Ziegler (Sampdoria).
Midfielders: Valon Behrami (West Ham), Gokhan Inler (Udinese), Benjamin Huggel (Basel), Gelson Fernandes (St. Etienne), Xherdan Shaqiri (Basel), Pirmin Schwegler (Eintracht Frankfurt), Tranquillo Barnetta (Bayer Leverkusen), Marco Padalino (Sampdoria).
Forwards: Alex Frei (Basel), Blaise Nkufo (Twente), Eren Derdiyok (Bayer Leverkusen), Hakan Yakin (Lucerne), Marco Streller (Basel).
