Kalou did not feature much under Avram Grant's successor, Luiz Felipe Scolari, except during pre-season, because of his participation in the 2008 Beijing Olympics as part of the Ivory Coast national under-23 football team. However, he came off the bench against Manchester United on 21 September and scored a header after 80 minutes from a John Obi Mikel free kick. The goal ensured that Chelsea secured a point and kept their unbeaten home record. Kalou then scored two goals and assisted a Frank Lampard header on 18 October in Chelsea's 5–0 win at Middlesbrough.
