Nicolas Jackson made it ten goals in 12 Premier League London derbies as the Blues beat West Ham United 3-0 this afternoon.
According to the official website of Chelsea, the Senegal international's composed first-half brace means the striker has now scored four goals in five Premier League matches this season.
Chelsea's victory at West Ham sees the Blues currently second in the table, although today's London Derby was the first Premier League match of the weekend, meaning the other 18 teams in the division do have a game in hand.
League leaders Manchester City top the table on 12 points, with Arsenal and Newcastle United also on 10 points but currently below us on goal difference.
Chelsea's next outing will be Tuesday night's home game with League Two Barrow in the Carabao Cup.
