From the quality of the most strongest German goalkeeper, which is actually available – how Ter Stegen comes back after his injury is in the stars.
Baumann and with cuts Nübel have a bit ahead, at least in terms of national and international experience, atubolu, but the point also takes nothing to Dahmen.
I would permanently rely on Atubolu as No. 1.
Baumann did his job as a temporary solution and should move into the second link. Nübel/Dahmen are good third goalkeepers.
