10. Andriy Shevchenko - 0.298
Shevchenko ahead of Gudjohnsen? You better believe it. The Ukrainian will always be labelled a 'flop', but only nine other Chelsea strikers have found the back of the net at a better rate than the AC Milan icon this century.
9. Nicolas Anelka - 0.32
One of Chelsea's best signings of the modern era. Anelka even won the Premier League Golden Boot during the 2008/09 season.
8. Michy Batshuayi - 0.324
There's no denying that the Belgian simply isn't good enough to be Chelsea's main man up top. However, his goal record with limited minutes on the pitch should still be appreciated.
7. Alvaro Morata - 0.33
Morata's Chelsea career started with a flurry of goals, but things turned sour very quickly. A goal every three games isn't bad going, though.
=5. Hernan Crespo - 0.342
The Argentine looked as if he was going to take the Premier League by storm in 2003, but his initial good form quickly deserted him and he was loaned to AC Milan after just a year with Chelsea.
=5. Samuel Eto'o - 0.342
Eto'o was coming towards the end of his career when he signed for Chelsea. Nevertheless, he found the back of the net at a very decent rate during his short stay in London.
4. Tammy Abraham - 0.4
Not bad Tammy, not bad. But despite his goal record, it looks like the Englishman will be competing with Werner for the striking role next season.
3. Didier Drogba - 0.43
Sometimes, stats aren't the finest assessment of a player. His ratio might not be the best, but Drogba is without doubt Chelsea's greatest ever striker.
2. Diego Costa - 0.48
The Blues splashed £32m on the bullish Spaniard and Costa was an instant success at Stamford Bridge. Why Antonio Conte was so desperate to sell him is anybody's guess.
1. Jimmy Floyd Hasselbaink - 0.49
One of the most underrated strikers in Premier League history. Hasselbaink scored goals for fun at Chelsea and he managed to do so in a pretty average Blues side, what a player!
So Hasselbaink just pips Costa to top spot. Despite Chelsea's success this century, they still haven't had a striker who has managed to deliver a goal every two games.
Can Werner be that man?
