Chelsea’s first involvement in the Carabao Cup this season got off to the perfect start, with the Blues managing to get six past Barnsley as Kai Havertz scored his first senior hat-trick in a 6-0 thriller. Here are five things we learnt from the latest match – and this time, there are positives all round (well, almost).

Kai Havertz Hat-trick

What better way to start this off, than a hat-trick from record signing Kai Havertz? The youngster has received some unfair criticism over the past two weeks, with spectators commentating on his underwhelming performances against Brighton and Liverpool. However, the 21-year-old looked superb in the Carabao Cup tie against Barnsley – scoring three goals. Yes, it may be against a Championship side that battled against relegation last season, but it was promising to see him link up well with fellow youngster Tammy Abrham, with the German playing in a number ten role behind the striker. Hopefully, this will give him the confidence boost he needed to go into the next Premier League game against West Brom.

Willy Caballero’s Still Got it

Although the spotlight was on Kai Havertz last night, Willy Caballero deserves a huge amount of praise for his work between the posts on Wednesday night. The 38-year-old continues to prove why he is such an important asset in this side, especially when it comes down to cup competitions. Although Barnsley had an impressive 9 shots on target, Caballero denied them – making some particularly good saves at the start of the match. With the Argentine able to prevent the Championship side from scoring in the early moments of the game, Chelsea were able to go through the match with confidence and secure an unusual clean sheet.

A Solid Performance by Tammy

Another youngster who has perhaps gained some unnecessary criticism lately has been our number nine. However, Abraham looked solid in the game against the Tykes – getting two assists and scoring the opener. In fact, Abraham was involved in all of Kai Havertz goals, with the two players looking like the perfect partnership on the pitch. His dummy for Havertz’s second goal was particularly easy on the eye, and Frank Lampard could have some thinking to do in terms of the attack going forward.

Emerson’s Back?

It’s been a while since we’ve seen Emerson play the full 90 minutes on the pitch. Therefore, when he was selected for the game against Barnsley, it’s fair to say that not many Chelsea fans were expecting big things. However, the 26-year-old had a good game on Wednesday as left-back, especially going forwards. When Ben Chilwell came on for his debut, the defender moved up onto the left and right wing, where he looked surprisingly comfortable. Could we see the Italian international play in this position in the future?

What’s Happened to Callum?

It’s a shame to say that one youngster on the pitch that didn’t particularly have a great game was Callum Hudson-Odoi. Although he had some promising moments at the start, he gave away the ball on several occasions and appeared sloppy at times. Perhaps the 19-year-old is still getting back to his best, and hopefully we’ll be able to witness that soon.
