Chelsea manager Frank Lampard was impressed by Kai Havertz’s performance on Wednesday after he netted a hat-trick in their 6-0 League Cup win over Barnsley at Stamford Bridge and said it was just the first of many great nights to come from him.

Havertz struggled in Premier League games against Brighton and Hove Albion and Liverpool but showed why Chelsea spent $90 million to get him from Bayer Leverkusen.

“We had to play him because we had a few injuries...The combinations he had with Tammy Abraham and the three goals were impressive,” Lampard said.

Chelsea face West Bromwich Albion on Saturday.
