Tbh even if we don't have a 'sweeper keeper' we still need one who isn't an umpa lumpa.
Hart cannot keep hoofing the ball to the opposition or into touch, in a Pep Guardiola team.
He may have been given license to do it short term, until he gets used to the way Pep wants him to play or he may have just ignored Pep & done it anyway. But his first few touches were crap.
If it's he latter, & he has ignored Pep's instructions, he's probably a gonner, very soon. Let's hope that's not he case, but Hamman seemed to have seen something.
