He also earned a call up to the Switzerland 2006 FIFA World Cup squad despite not playing in the qualifiers and only getting his international debut in March. He then signed a six-year contract extension with Arsenal after the competition.
Djourou has continued to struggle for regular first-team action, with injuries, poor form and competition for places all playing their part. He featured 22 times in the league during the 2010-11 campaign but has since slipped down the pecking order following the additions of Laurent Koscielny, Thomas Vermaelen and Per Mertesacker. In spite of this, it was reported in February 2012 that Djourou had signed a three-year contract extension until summer 2015.
