Chelsea boss Thomas Tuchel has broken an English derby record with victory at Brentford.

Chelsea are the first team ever in the top four tiers of English football to win seven consecutive London derbies, and they did so by only conceding one goal.

The incredible stat highlights the impact Tuchel has made since taking over from former manager Frank Lampard, and it's just one of many stats that have put the German in the conversation as one of the best managers in Europe, reports the Mirror.

The Blues have more clean sheets than goals conceded under Tuchel since the German arrived at Stamford Bridge, and it's by no fluke that the European Champions sit top of the Premier League, with the capability of defending their Champions League crown.

To make up Chelsea's incredible record away in London, they have beaten Fulham, Crystal Palace, West Ham, Arsenal and Brentford, and have been victorious twice against Tottenham to complete the run.
