Has Pep never watched a premier league game? Getting in a keeper who can't deal with crosses is a massive mistake. As we know.
The whole of City's defence is shite. As is united's midfield.
Some managers seem to think they need to make a big change, almost regardless of whether it's needed or not, when they start a new job. I suspect that Guardiola is very likely to do something like that and that it played a large part in this decision, which could certainly bite him on the @rse.
