The disastrous loan spells of Falcao from Monaco and Alexandre Pato from Corinthians this season mean that Chelsea fans can add two more to a somewhat long list of forwards that have failed at the club.
Didier Drogba is arguably Chelsea's most successful forward, scoring 104 goals in 254 games across two spells at the club. He helped the Blues win four Premier League titles as well as the Champions League in 2012 - the final game of his first spell at the club.
Unfortunately, not every forward at Stamford Bridge has made the same impact, or indeed got anywhere near doing so.

With Pato and Falcao already mentioned they aren't included in this list, but here are five more Chelsea striker flops who arrived with big reputations.
Andriy Shevchenko (48 games, 9 goals)
Shevchenko burst onto the scene in his home country with Dynamo Kiev, scoring 18 times in 26 games in the 1998-99 season.
That earned him a move to Italian giants AC Milan, where he would become one of their most decorated players of all time.
He scored 24 goals in three of his eight seasons at the club, and only twice failed to reach double figures.
He helped the Rossoneri win the Serie A in 2003-04 and the Champions League in 2002-03.
This excellent record persuaded Chelsea and then manager Jose Mourinho to splash out over £30 million, but his time in England was disappointing.
The Ukranian hotshot scored just nine times for the Blues and spent just two full seasons at the club.
He returned to Milan on loan and then back home to Dynamo before retiring in 2012.
Salomon Kalou (156 games, 36 goals)
After an impressive tally of 35 goals in 69 appearances for Feyenoord, the Ivorian spent six seasons at Chelsea, during which he won a Champions League, a Premier League title and four FA Cups.
However, his goal record left a lot to be desired, as he averaged a goal every five games, despite usually playing as a second striker.
For the number of games he played, Chelsea fans could be forgiven for having expected more goals from the now 30-year-old.
Mateja Kezman (25 games, 4 goals)
The Serbian goal getter first came to attention following two outstanding seasons at PSV - he scored 66 goals in his final two seasons at the club.
This form caught the eye of Chelsea who made Kezman one of their top purchases in the summer of 2004, for just over £5 million.
Following his success in Holland, it was hoped that he could replicate the same displays in England. This wasn't the case as Kezman failed to impress, and left after just one season.
Adrian Mutu (27 games, 6 goals)
The Romanian's career was heavily blighted by drug scandals and subsequent suspensions, one of which occurred while at Chelsea - making him a vilified figure with supporters.
Mutu moved to London from Parma in 2003 for around £22 million, but failed massively to live up to the enormous price tag.
He scored six goals in his debut season but for the price paid, Chelsea fans were expecting far more from the controversial forward.
Following a failed drugs test the following year, Mutu was suspended and eventually released by Chelsea.
