Chelsea are now the only club left unbeaten in Europe's top five leagues in all competitions after Manchester United's stunning win over Juventus in Turin.
Juventus looked odds-on to continue their unbeaten streak as Cristiano Ronaldo's stunning volley saw the Italian champions leading with four minutes to go.
However, Juan Mata's sumptuous free-kick hushed the Juventus faithful and Alex Sandro's late own goal secured a win in Turin that breathes new life into the visitors' Champions League campaign.
With Juventus' unbeaten run now over, Maurizio Sarri's Chelsea are the sole team across Europe's top five leagues who are yet to have lost a game this term.
Chelsea have not been quite so imperious in the Premier League, where they are one of three unbeaten teams but have drawn three of their 11 games so far, one more than league leaders Manchester City.
Both City and Liverpool have been beaten in the Champions League while Sarri’s men have won their four Europa League games at something of a canter.
The Blues unbeaten run was put to the test on Thursday when they won Belarussian champions BATE Borisov in Barysaw by a slim margin.
