Roberto Di Matteo has warned his Chelsea side they risk making the wrong kind of history if they fail to take Wednesday's Champions League clash with Benfica seriously.
The Blues, who became only the fourth club ever to overturn a two-goal first leg deficit when they beat Napoli to reach the quarter-finals, need only draw the second leg to avoid becoming the third side to crash out after a first-leg away win.
Complacency would therefore appear to be the biggest threat to Di Matteo's men setting up a mouthwatering tie against Barcelona or AC Milan, and he cautioned: "It is a danger. This is half-time and we're leading 1-0. But a 1-0 lead is basically nothing."
