Their fantastic defensive record is down to how settled their backline has been throughout the season.
Another defensive rock has emerged in recent weeks and that man is Kurt Zouma, who was signed from Saint Etienne last year.
The 20-year-old was recently compared to Marcel Desailly by his manager Jose Mourinho, as reported by the Daily Express, and you can certainly see why.
While Zouma has been filling in for the suspended Nemanja Matic in defensive midfield recently, his natural position is at centre-back and he has the potential to be Terry’s long-term heir.
He is very much in the Terry mould but he also has more versatility in his game. Zouma is a no-nonsense defender but is also adept at playing out from the back and has proved he can play in two different positions.
The Frenchman has won 57% of his tackles, 76% of his aerial duels and averages over four clearances per game at Chelsea this season.
