He has no plan. His plan is to work with what he has, smile for the cameras and act like he knows something others don't. Simple as that. You have to bear in mind, the United job is literally Ole's Holy Grail. If he finished 8th every season but wasn't fired, he'd be loving life because this is a club he genuinely loves and loves working with. He has been saying the right things in the eyes of the board, but in football terms he's proving to be as limited as David Moyes.
The only thing that saves this football club is hiring a young, progressively minded coach and backing him with a load of money to upgrade on Lindelöf, Shaw, McTominay, Lingard and (sorry about this) Rashford. That's 5 first team players that are not quite good enough in some instances (Rashy and Shaw) and definitely not good enough in others (Lindelöf, Scott, Lingard). We need an overhaul every single summer and we don't get it. Last summer we bought a £50m midfielder in Fred who cannot evn get into the matchday squad. We lost Herrera on a free, who, while not being world-class, was way better at his role than McTominay. Our inability to sign a midfielder means that Matic has been rightfully benched, but means Pogba is being played further back as a result limiting his impact on us actually scoring goals and creating anything.
He's a much more likeable David Moyes. If he never played for United, he would never have even got the caretaker job. Simple as that. The fact he's now the main man, having won 3 out of 17 games in his last 20+, is mental. Reap what you sow.
