It was a well-known fact before the game against West Ham, but the goalless draw seemed to show once again the need that Chelsea have for an out-and-out striker.
They need someone who will stay in the box, make runs to the front post and score headers from crosses.
Didier Drogba has never been replaced at Chelsea and this season Jose Mourinho has Fernando Torres, Demba Ba and Samuel Eto'o at his disposal - players who simply cannot be expected to lead a title charge.
With Robert Lewandowski choosing Bayern Munich, Edinson Cavani and Radamel Falcao unavailable after summer moves to France and Wayne Rooney likely to sign a new contract at Manchester United, alternatives look hard to come by.
In the following, three strikers will be assessed, who would be ideal in front of the likes of Oscar and Hazard, whilst also being available and willing to move.
Edin Dzeko | Value: £20m
Edin Dzeko is a goal machine. He has a phenomenal goals-to-games record and even though he has been overlooked at Manchester City in favour of Balotelli and Tevez and then Negredo and Aguero, he still manages to notch up an impressive tally.
The Bosnian striker is in red hot form at the moment but it is expected that Pellegrini will revert back to the successful Aguero-Negredo partnership soon.
Dzeko is a strong and tall striker who can score with both feet and his head. He is what one might call a "complete striker" and if he were at Chelsea he would surely turn their many attempts into goals. Dzeko has a direct approach that allows his to be very prolific whilst also acting as a target man when his back is to goal.
If Manchester City decided they were willing to sell the Bosnian, Mourinho should do all he can to sign the man who has been linked to many top clubs including Arsenal, Dortmund and Inter Milan.
Javier Hernandez | Value: £13m
Hernandez is a typical "goal-hanger" similar to Ruud van Nistelrooy. It is very rare for "Chicharito" to score 25-yard thunderbolts or curlers from the edge of the box.
Instead, Hernandez scores from inside the six yard box. He lingers where defenders find him a nuisance and he is the first to pounce when there is a ball to be won. His goal against Sunderland in the second leg of the Capital One Cup and his recent goal against Chelsea are perfect examples of what he is capable of.
If you put "Chicharito" through on goal, it is game over for the goalkeeper. If you put a cross into the six yard box, he will win the header despite being shorter than most central defenders.
Similar to Dzeko, he has been consistently deadly in front of goal but is overlooked due to the presence of Robin van Persie and Wayne Rooney, who are ahead of him in the pecking order.
However, at Chelsea he would provide the destructive finishing that has been missing from the Chelsea game ever since Drogba's departure in 2012. Also, with a transfer value of 'only' 13 million Pounds, he is the most affordable of the options.
Diego Costa | Value: £25m
Diego Costa is the name around the block at the moment. He has burst on to the scene this season with Atletico Madrid, ensuring that they are still gunning for what would be an astounding La Liga title. Costa is a mixture of strength, speed and skill.
With 24 goals in 31 appearances this season, including 19 in the league and four in three games in the Champions League, he is firing from all cylinders. It takes a special player to be just three goals behind Ballon d'Or winner Cristiano Ronaldo going into February.
Whilst Costa is still relatively unproven, he would make a fine addition to the current Chelsea squad. He has been linked profusely and there was talk of a Costa-Courtois swap deal before Jose Mourinho dismissed it. It is not beyond the realms of possibility that Atletico Madrid will ask for Fernando Torres back. This deal would be perfect for everyone involved.
Mourinho and Chelsea would get the world class striker they desperately need whilst avoiding paying the reported £32m Atletico Madrid are asking for.
Atletico, in turn, get good money and a solid replacement who is also a fans favorite. The players also get what is best for them. Costa moves forward in his career, whilst Torres will have a last chance to revitalise his one at a club he loves.
Chelsea desperately need a striker and there is a very limited choice at the moment. Mourinho will need to ascertain who is available, worth getting and not too expensive that Chelsea run the risk of upsetting the guidelines of FFP.
It will be interesting to see who will be able to make the strikers position their own at Stamford Bridge and Chelsea fans will be hoping that whoever that is will follow in the footsteps of Didier Drogba and not Fernando Torres.
