The senior side, overseen by Tuchel, will face Spain in the opening fixture of the new Nations League cycle, before tackling Croatia at home and away and Czechia over the next ten days.
Two Under‑19 internationals – Manchester City’s Kaden Braithwaite and Tottenham’s Malachi Hardy – were invited to join the senior training session on Wednesday to help fill numbers, a move Tuchel described as a chance to give younger talent exposure to the senior environment.
On Monday, late additions Morgan Gibbs‑White and James Garner were called up after five players withdrew from the camp due to minor injuries, highlighting the depth concerns ahead of the Spain clash.
Tuchel is expected to field a strong XI against Spain, with only Trent Alexander‑Arnold listed as a specialist right‑back. He may opt to use midfielder James Garner or centre‑backs Ezri Konsa and Jarell Quansah in a more defensive setup if required.
The absences of Declan Rice, Jamal Mainoo, Jordan Henderson and Reece James open the door for fresh midfield options alongside Elliot Anderson, with Myles Lewis‑Skelly and Bournemouth’s highly rated Alex Scott named as possible contenders.
If captain Harry Kane features in all four matches over the next two weeks, he will equal Peter Shilton’s record as England’s most‑capped player.
