Olé could be a success, he may have the managerial ability, and tactically at times he has looked very good especially during his golden start, a start he deserved great credit for as it continued after the expected initial easy fixtures and bounce but this is but a small, even tiny, part of any managers skill set.
When things have gone wrong, as of now, is a new test, the players have reverted to their earlier under achievement and the task is seen for the enormous job it is.
It's far harder for any manager when the wheels fall off, especially if the underlying reasons are beyond his control atm and need extensive reconstruction involving time and transfer windows.
He'll be given the chance and as he's so unproven, may be a success or an abject failure, the jury is out, there is far too little evidence to make a judgement either way. Unlike Pep or Klopp there is no suitable credible evidence from previous posts to inspire confidence only the fact that he was a great player in his time.
Solskjaer to me is a huge risk, has an enormous job on his hands, and may pass or fail, but given the enormity of it it will possibly be more surprising if he can complete it with any real degree of success. A technical director appointed yesterday or last month would help enormously, this is far too big a job for even a far more experienced and perhaps far more suitable candidate, help is badly needed.
With Poch, United could have given him £500million to spend. Levy will give him £50milllion if that. (Over a period not one window)
Solskjaer is an absolutely huge risk and one they didnt have to take.
