Chelsea thrashed Arsenal reserves 4-0 yesterday.

Teenage defender Nathaniel Chalobah struck twice, while Romelu Lukaku and Lucas Piazon were also on the scoresheet.

Chalobah, playing in deep midfield, netted a clever back-heel to open the scoring seven minutes before half-time, adding a third from a sumptuous free-kick after Lukaku had clipped home a second goal five minutes into the second period.

Piazon completed the goalscoring shortly before full-time with a cute solo effort, twisting and turning inside the area before firing home.
