I actually agree with what one of the pundits said recently, was it Carragher? Maybe Joe should have been proactive when it was clear Pep was joining, and worked on changing his game. It is pretty clear to me what Pep is looking for in a goalkeeper and perhaps Joe should have spent more time looking at the keepers that were playing for Pep and try to adjust.
For all we know he did try, when we treat assumptions as facts things can get very confusing.
