On 14 January 2009, Kalou scored a tap in against Southend United in the third round of the FA Cup as Chelsea ran out 4–1 winners in the replay. Again he scored two goals against Middlesbrough, this time at Stamford Bridge on 28 January, a 2–0 Chelsea win, becoming a favourite under interim manager Guus Hiddink. These strikes proved to be his first goal in 15 Premier League games. He celebrated the goals by making a "handcuff" gesture, but denied he was supporting an Ivorian convictionist. On 25 April 2009, he scored the winner against London rivals West Ham. Kalou was an unused substitute in Chelsea's 2–1 defeat of Everton as the Blues won the FA Cup on 30 May.
