Eddie Nketiah admits he's concerned about his playing time at Arsenal.
The striker will captain England's U21 in the European Championship group stage this week.
Bu there are concerns around Nketiah's match fitness, with the 21-year-old making 14 league appearances this season.
"It's been a difficult month or so for myself. I've not played as much as I'd like to but I've worked hard and stayed dedicated," he said. "I've got a great opportunity in front of me and Aidy was in communication throughout.
"I've a big tournament ahead of me and I'm grateful for the opportunity to achieve something special. It's a big honour to even represent your country in a major tournament, nevermind be captain.
"To get that responsibility is a great feeling and one I'm proud of. I'm looking forward to getting onto the pitch and contributing to something special. I was delighted, smiling [when told by Boothroyd]. I'm grateful for the opportunity and the responsibility he's given me."
The Young Lions take on Switzerland on Thursday before facing Portugal and Croatia.
