Carabao Cup: Kai Havertz Scores Hattrick As Chelsea Thrash Barnsley 6-0

Kai Havertz scored his first goal for Chelsea with a hat-trick in a 6-0 thrashing of Barnsley as Thiago, Chilwell makes debut appearances.

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.

Thiago Silva and Ben Chilwell also made their Chelsea debuts, while Tammy Abraham and Ross Barkley made the most of rare starts to get their names on the scoresheet.

The 21-year-old German was one of just three players to retain his place from Sunday's 2-0 defeat to Liverpool by Frank Lampard and that decision reaped its reward on a confidence-boosting night for the Blues.

Abraham pounced on a loose pass deep in the Barnsley half to slam home the opener before Havertz's calm finish opened his Chelsea account.

A brilliant unselfish flick from Abraham teed Havertz up perfectly to convert his second and Barkley then drove home on his weaker left foot.

Havertz was due to be replaced by Chilwell 25 minutes from time but just completed his hat-trick in time by rounding Brad Collins before tapping into an empty net before Olivier Giroud completed the scoring.

Chelsea will face either Tottenham or Leyton Orient in the last 16 with the outcome of that tie yet to be decided after the match was postponed on Tuesday due to a number of coronavirus cases among the Orient players.
