Swansea City's
Liberty Stadium. Chelsea kept up hope of qualifying from their Champions League group by defeating Shakhtar Donetsk 3–2 at home with an injury-time winner from Victor Moses on 7 November. The victory put Chelsea on top of Group E with two games to play. Chelsea then failed to win for their fourth Premier League match in a row after

2011–12 FA Cup for Chelsea. On the same day, former
Liverpool manager
Rafael Benítez was appointed as the club's
interim manager until the end of the season. His first act of his tenure was to name Dutchman
Boudewijn Zenden, a former Chelsea midfielder who had played under him at Liverpool, as his assistant. Chelsea midfielder Mikel John Obi was charged with misconduct by the FA after his allegations of racial abuse against referee Mark Clattenburg in the October fixture against Manchester United were found to be baseless. Benítez's first game in charge was a goalless draw with
2011–12 Premier League winners Manchester City on 25 November. Despite not scoring, Chelsea kept their first clean sheet since the 1–0 win over Stoke City on 22 September. The club's next game, a
West London Derby against

Sunderland 1–3 away with Fernando Torres scoring a
brace. The victory was Chelsea's first league win in eight matches. Chelsea entered the
2012 FIFA Club World Cup at the semi-final stage, where they beat
CONCACAF champions
Monterrey of Mexico 3–1 on 13 December, before losing 1–0 in the final to
Corinthians of Brazil in the
Yokohama Stadium three days later.
Gary Cahill was sent off in injury time for violent conduct towards Corinthians'
Emerson. The club returned to England with a 5–1 home victory in the League Cup against
Leeds United on 19 December, coming from a goal down at half-time to reach the semi-finals of the tournament. The club's first Premier League match since the Club World Cup was an 8–0 victory over
Aston Villa on 23 December, followed by a 0–1 win at Norwich City's
Carrow Road three days later. A third consecutive Premier League victory was confirmed in the last match of 2012, which saw Frank Lampard score twice as Chelsea came from behind to win 1–2 away to

Daniel Sturridge to
Liverpool for an undisclosed fee reported to be £12 million. Sturridge played 96 games for Chelsea in three-and-a-half seasons, scoring 24 goals. The year opened with a 0–1 home defeat to bottom-of-the-table West London rivals QPR, with the goal coming from former Chelsea winger
Shaun Wright-Phillips. However, Chelsea made progress in the third round of the
FA Cup, where they beat
Southampton 1–5 away at
St Mary's on 5 January. Ba scored twice on his debut, while
Frank Lampard scored his 193rd goal, moving him equal to
Kerry Dixon as Chelsea's second-highest goalscorer of all time. On 9 January, two defensive mistakes from defender
Branislav Ivanović caused a 0–2 home loss in the League Cup first semi-final leg tie against Swansea City. In their next Premier League match, on 12 January, Chelsea ended Stoke City's 17-game unbeaten home run by winning 0–4 away. Lampard's converted penalty, his 194th goal, moved him above Dixon's total. However, the following home match against Southampton on 16 January saw Chelsea give away a 2–0 half-time lead, opened by Ba's first Premier League goal, to draw 2–2. The Blues then defeated
London rivals Arsenal 2–1 on 20 January, with early goals from
Juan Mata and Frank Lampard cutting Chelsea's deficit behind second-place Manchester City to six points. On 23 January, Chelsea drew the second leg of their League Cup semi-final against Swansea City, which sent Swansea through to the final. Chelsea's
