Gareth Southgate says England's future is "really exciting" days before the start of Euro 2020.
The Three Lions take on Romania in a friendly on Sunday - one week before their opening Group D fixture with Croatia at Wembley.
Southgate has injury issues concerning several experienced players before Euro 2020 starts, but believes his young players can impress at the tournament.
"Some of them have 10 caps or more at a young age," he added.
"In the long term that will be really beneficial."
Southgate has lost Mason Greenwood to injury for the tournament, one of three teenagers named in his 33-man provisional squad.
But 17-year-old Borussia Dortmund midfielder Jude Bellingham, plus Arsenal's Bukayo Saka, 19, are expected to feature.
