Half-time: Koulibaly scores stunning volley, Chelsea lead against Tottenham (video)

Chelsea have been excellent against their London rival Tottenham.

The Blues took the lead in the 19th minute courtesy of Kalidou Koulibaly’s stunning volley.

The goal was from a corner kick.

Cucurella crosses it in and Koulibaly who was left unmarked punished the Tottenham set-up.

With the display by Tottenham, Conte has work to do at half-time.

Tottenham have won just one of their last 37 away matches against Chelsea in all competitions and they will need to do more to overturn the bad runs.
