For the Premier League’s biggest clubs, this competition is often an opportunity to blood youngsters and give valuable minutes to fringe players. However, only 35-year-old Danny Welbeck, who scored two goals, emerged from the starting lineup with a compelling case for more regular participation. Even Valentin Barco, despite scoring Chelsea’s fifth goal, was partly to blame for Leeds’ second and was among several players who repeatedly gave up possession during a difficult first half. Young attackers Estevao Willian and Jamie Gittens suffered the disappointment of being substituted at half-time, while £40million signing Geovany Quenda, who arrived from Sporting, was left out of his only substitute appearance for the club as he watched from the bench. Midfielder Reggie Watson, who made his debut at the age of 16, was also taken off at half-time after being booked.

They have a 27-man squad, backed by a strong academy portfolio, and these matches are vital to maintaining a high match count. group of players committed throughout the campaign. It is an irony, then, that Palmer, Rogers and other established Chelsea stars may have secured future opportunities for fringe players whose performances had put the club’s EFL Cup campaign at risk.
