Valon Behrami and Jonathan Spector look likely to feature at the 2010 FIFA World Cup after being named in the Switzerland and United States squads respectively.
Midfielder Behrami has been a regular member of Ottmar Hitzfeld's squad since making his international debut in a 2006 World Cup qualifier against France in October 2005, earning 26 caps in total.
The 24-year-old played at the 2006 World Cup finals in Germany, only for a knee injury in the final group-stage fixture against Korea Republic to restrict his participation to just two minutes as Switzerland reached the second round.
Behrami will link up with Hitzfeld's squad for pre-World Cup friendlies against Costa Rica on 1 June and Italy on 5 June respectively. Switzerland begin their World Cup challenge by facing Spain in Durban on 16 June.
