Chelsea kicked off their Carabao Cup campaign in style with an emphatic 6-0 win over Barnsley.
Kai Havertz opened his Blues account with a fantastic hat-trick, while goals from Tammy Abraham, Ross Barkley and Olivier Giroud also helped the hosts cruise into to the fourth round of the competition, where they look forward to visiting either Tottenham Hotspur or Leyton Orient.
Frank Lampard's men dominated throughout the majority of the tie, with Thiago Silva and Ben Chilwell making their Chelsea debuts.
Here's what we learnt from tonight's one-sided affair:
Havertz stars in Number 10 position
It's fair to say it's been a difficult start for the £72 million pound man, who found himself out of position against Brighton and sacrificed for defensive cover at half-time against Liverpool.
However, despite facing Championship opposition, the German international looked unstoppable in possession, linking up well with fellow attackers Tammy Abraham and Mason Mount to create countless chances for the Blues, three of which being taken well by Havertz.
Lampard's selection of Havertz showed the Chelsea boss was keen for him to find his feet in English football, after previously stating all of his new signings would need time to adapt to their new surroundings.
Nevertheless, the 21-year-old will gain a lot of confidence from his individual performance, as he looks to make a mark on the Premier League in upcoming fixtures.
Thiago Silva leads by example
If you'd have asked Thiago Silva who he thought his next opposition would be following the Champions League final in Lisbon last month, Barnsley would probably not have been his first answer.
However, the former PSG captain looked confident and assured in his first appearance in Chelsea blue.
The Brazilian came away from his hour-long debut with 100% success in aerial duels and tackles, as well as completing 94% of his passes in a game where he never looked in any trouble.
Defensive issues have always been a concern since Frank Lampard took over the club, so the acquisition of one of Europe's most accomplished centre-back's will surely be important throughout the season, despite the fact he is entering the twilight of his career.
Caballero states his case
While Chelsea were dominant throughout and could have scored more than the six they did, Barnsley had nine shots on target, mostly in the first half.
Willy Caballero was forced into a number of impressive saves throughout the tie, keeping Chelsea's first clean sheet of the season.
Earlier this week, Frank Lampard all-but confirmed the acquisition of 28-year-old Edouard Mendy, with Kepa Arrizabalaga again coming into question after his mistake against Liverpool.
It is unlikely Mendy will be occupying the Number 1 shirt permanently straight away, meaning the 38-year-old Argentine will feel he still has a number of appearances at Stamford Bridge in him, going into what could be his farewell season from football.
