Chelsea have qualified for the next round of the Carabao Cup after thrashing opponents Barnsley 6-0 at the Stamford Bridge on Wednesday night.

New Chelsea signing, Kai Havertz opened his goal-scoring account for the club with a hat-trick as the Blues trash Barnsley.

Havertz had struggled to make an impact in his first two Premier League games since sealing a reported £71 million ($94 million) move from Bayer Leverkusen as the most expensive signing of Chelsea’s £200 million spending spree in the transfer market.

“I am delighted with Kai, it was everything I wanted from him,” said Lampard.

“He had no pre-season so I wanted to give him more time on the pitch with his teammates, learning how we play and press. It was a great night for Kai and it is the first of many for him.”

Teammate, Ross Barkley, Olivier Giroud and Tammy Abraham were also on the scoresheet on the night.
