The Spain international's contribution to Antonio Conte's side's impressive assault on the league this season has been an important one and he is undoubtedly one of the most effective midfielders in the division in terms of goals and assists.
Fabregas has scored three goals and provided seven assists in the Premier League this term, meaning that he has been directly involved in more goals than Arsenal's Mesut Ozil (five goals, four assists) in the current campaign.
What's more, the former Barcelona man has achieved that feat despite having been on the pitch much less than Ozil, playing 1227 fewer minutes than the Gunners playmaker.
Amazingly, Fabregas was one of four Spanish goalscorers in the game between Chelsea and Swansea, with Pedro, Diego Costa and Fernando Llorente also finding the net at Stamford Bridge.
That is the joint-highest number of players of a single nationality excluding English scoring in a Premier League match.
The only other game in Premier League history in which four players from the same country scored came 14 years ago, back in February 2003, when Arsenal thrashed Manchester City 5-1 at Maine Road.
French stars Thierry Henry, Robert Pires and Patrick Vieira got on the scoresheet for Arsenal, while Nicholas Anelka found the net for Man City.
