Gareth Southgate is set to experiment with a back three against Germany in Dortmund on Wednesday night, with Michael Keane poised to win his first England senior cap.
Manager Southgate has kept his team for the friendly a closely-guarded secret, refusing to even tell his players the line-up on Tuesday night so it did not leak.
But Telegraph Sport understands that Southgate is expected to start Keane in a three-man defence with captain Gary Cahill and Chris Smalling.
