Agree 100%.
As you say, I think Wimmer clocked really quickly what resources he had available and was savvy enough to adapt and find a way to get us over the line pretty comfortably. Concern would be that JBA isn’t prepared to shift (much or at all) on his principles (a bit like a certain Russell Martin at Southampton- yes, yes, different league etc. but similar issue) despite the personnel available - then it could be tough for everyone!
But ………… gotta trust the guy, have faith, strap in for what could be a very interesting season ahead.
