   • 2011 October 2, Jonathan Jurejko, “Bolton 1 - 5 Chelsea”, BBC Sport:

     And with Bolton suffering a wretched run of five straight home defeats - their worst run in 109 years - Chelsea fans would have been forgiven for expecting a comfortable win.
     But surely they did not anticipate the ease with which their team raced into an almost impregnable half-time lead.
