There is an old joke about two idiots watching a cowboy film. John Wayne rides his horse over a cliff. 'Let's watch it again,' says one of the idiots. He bets £5 on the outcome. Wayne rides his horse over a cliff again. 'I can't believe it,' said the idiot, paying up. 'I never thought the silly bleeder would do it a second time.'
That was pretty much like Chelsea on Wednesday night. They conceded one goal from Dele Alli just before half-time; and then just after half-time they conceded the same goal again.
Seriously, same goal.
