Liverpool right-back Trent Alexander-Arnold was drafted into England training on Tuesday.
With the World Cup three months away, Gareth Southgate's preparations continue with warm-up friendlies against Netherlands and Italy over the next week.
Southgate's 27-man squad are at St George's Park ahead of Friday's match in the Netherlands, with a number working on individual training schedules away from the main session on Tuesday.
Adam Lallana and Ryan Bertrand were among those inside, while Marcus Rashford, Jake Livermore and James Tarkowski left the main group before the session had finished.
Southgate brought England under-21 defender Alexander-Arnold into the session to help bolster numbers, with the teenager taking part in an attack versus defence drill.
The 19-year-old has regularly rotated with England defender Joe Gomez at Liverpool this season, making 22 appearances in all competitions.
Meanwhile, uncapped Nathaniel Chalobah has joined the England camp after being invited by Southgate to continue his rehabilitation with them this week, Press Association Sport has reported.
Watford midfielder Chalobah has been out with a knee injury since September and is undergoing rehab at St George's Park.
The former Chelsea player is reported to have been visiting the national football centre in Burton for treatment on and off for a while, with Southgate inviting him into the camp.
