Until this match reached a frantic climax with 10 minutes remaining, the only real fireworks at Chelsea v Bournemouth had been during the pitchside pyrotechnic display.

The midweek Carabao Cup quarter-final seemed to be heading to 0-0 and penalties, until sub Eden Hazard latched on to a Pedro flick in the Cherries’ box and fired. His shot took a huge deflection off Charlie Daniels’ hand and flew past Artur Boruc.

In the last, chaotic minutes, Bournemouth had a string of close-range shots on goal, but the Blues smothered the danger to set up a two-legged semi-final clash against arch rivals Spurs in January.

It was a frustrating first hour in this close, but largely uneventful match. But a run of clever substitutions by Morrie Sarri, bringing on Pedro, Eden Hazard and David Luiz, tipped the scales in Chelsea’s favour.

The manager couldn’t hide his frustration at times, but the result pushes him a step closer to gaining his first trophy.

The first leg is at Wembley on either January 8 or 9.
