His 21 goals last season fired Chelsea to the Premier League title, but this campaign, Diego Costa appears more interested in hitting centre-backs than the back of the net.
The former Atletico Madrid hitman has just four goals in 17 games in all competitions, whilst Loic Remy remains a peripheral figure at the club and it has become abundantly clear the days of Radamel Falcao making defenders quake in their boots are over.
The Blues have scored just 21 goals in 17 league games this season - evidence they require a new centre forward and must dip into the January transfer window. Here are three strikers who could save their season.

The 26-year-old has made clear his desire to leave current club Sao Paulo for a European side in January, telling the Telegraph: "I would like to come to England because I think the championship [the Premier League] is the No1 in the world."
Pato fuelled speculation of a potential move to the champions when pictured at Stamford Bridge for Chelsea’s Champions League clash with Porto, and would be available for £15 million.
Former Blackburn flop Kalinic could be offered a route back to English football by Chelsea amidst reports in Italy that the Blues are set to move for the Fiorentina hitman in January.
Kalinic has been in lethal form for La Viola this term, sitting joint second in the Serie A top scorer charts after hitting ten goals in 16 league games and leading his side's title charge this term.
Any move for the Croatian, however, could be snagged, with reports suggesting he’s in love with Florence and convinced he can win something with Paulo Sousa’s side this season.
Belgian forward Batshuayi has scored 11 goals for Marseille this season, with the striker currently on the radars of several Premier League sides.
The quick and skillful forward has the potential to galvanise the Chelsea's front line given the distinct lack of pace and movement present at Stamford Bridge.
He's likely to command a price tag in excess of £20 million which the Blues will have no issue matching.
