Chelsea boss Antonio Conte dangled the carrot of additional game-time to his fringe players after the much-changed Blues blitzed Championship outfit Nottingham Forest to reach the Carabao Cup fourth round.
Striker Michy Batshuayi grabbed his first Chelsea hat-trick, while there were also goals for Kenedy and Charly Musonda, as Eden Hazard marked his first start of the season with two assists.
Conte made nine changes to the side which drew 0-0 with Arsenal on Sunday and threw on three teenage British substitutes – Ethan Ampadu, Jake Clarke-Salter and Dujon Sterling – in the second-half.
“We are a great club so every competition is important to us,” said Conte, who side were drawn at home to Everton in round four.
“We have to be competitive in every game and if the players answer like they did tonight I will continue to give opportunities. We must go game by game but when I have this type of answer I’m very happy.”
Kenedy, who was sent home from Chelsea’s pre-season tour of China following derogatory social media posts, volleyed home the opening goal on 13 minutes before Batshuayi tapped in his first.
Musonda drilled in Chelsea’s third on his full debut before Batshuayi snared his second following impressive approach play by Hazard.
The 23-year-old then completed his treble from on the goal line with four minutes remaining. On-loan Everton midfielder Kieran Dowell netted a late consolation for Forest.
