For Karim Benzema, a second consecutive Champions League hat-trick. For Chelsea, as milestone of a different sort.
When Real Madrid’s second went in it was the sixth opposition goal scored at Stamford Bridge without reply – starting with the first of Brentford’s four on Saturday. That is a first for the Roman Abramovich era.
The last time Chelsea were six in arrears at home Ken Bates was chairman and it was a previous century. Michael Hughes scored an equaliser for Wimbledon on December 26, 1997 – and on January 4, 1998, Manchester United raced to a 5-0 lead in an FA Cup.
