Here are the top five stats from the Blues' emphatic victory:
1) Fernando Torres took 39 Premier League matches to score four goals for Chelsea, whilst it has taken Diego Costa just three. The Brazilian-born Spain international has now netted four times this season, having converted 57.1% of his chances. He hit the target from 100% of his attempts against Everton.
2) Cesc Fabregas proved a creative force for Chelsea again in this tie. The Spaniard fashioned three chances for the Blues, providing the assist for Costa's opening goal. Jose Mourinho's £30 million summer signing has been extremely impressive since making his return to the English top flight. Thus far, he has played 10 key passes, assisting four strikes.
3) Leighton Baines recorded more touches than any other player in this match (106); he also fashioned the most number of passes (61). The former Wigan Athletic full-back completed 92% of his attempts to find a team-mate, whilst creating three chances. On the right side of defence, Seamus Coleman played the same number of key passes, assisting his third goal of the season.
4) Nemanja Matic's man-of-the-match performance saw him put in a remarkable shift. The Serbian midfielder scored his first ever goal for Chelsea, while creating two chances (one assist), winning three interceptions and completing seven turnovers for his side.
5) Tim Howard became the first goalkeeper to save a Diego Costa shot this season. It took 221 minutes of Premier League action.
