Drogba continued scoring goals but suffered an injury at the training ground and decided to have an operation on his knee. He was unable to play for four weeks and missed key games against Valencia, Arsenal and Liverpool. Drogba returned from injury to play in an FA Cup third round match against Queens Park Rangers and wore the captain's armband for the last 30 minutes he was on the pitch, but that was his last performance for Chelsea before international duty at the Africa Cup of Nations. Upon his return, Drogba scored a goal in the 2008 League Cup Final, making him the all-time leading scorer in League Cup Finals with four goals, but could not help prevent Chelsea fall to a 2–1 defeat at the hands of Tottenham Hotspur. He scored both goals in a key 2–1 victory against Arsenal on 23 March 2008, bringing Chelsea equal on points with leaders Manchester United.
