In fairness, you can tell what he's trying to do. He's trying to build a better culture at the club, clearing out those deemed "bad characters" and building that character around "United players" who have come through the academy and the club feels have been "brought up the right way".
As a style, he wants to play higher tempo football in attack with attackers who can play all across the front line, more pressing without the ball and a defence who can play out from the back.
Unfortunately, a rebuild like that will cost about £1bn as the club is utterly inept in the transfer market, so he's only been able to add 2 expensive defenders and a cut price winger, leaving the attack and midfield the weakest at the club in about 30 years.
So now, the team is completely dependent on a solid defence and pace on the counter attack or a bit of luck to break the opposition down. There are no goals in the team and they're set up to aim to win games by the odd goal. As a result, every mistake to gift a goal or penalty not given is a hammer blow.
One attacking player (Martial/Rashford) hitting a red hot streak of form would make a huge difference to this team and would turn frustrating draws into wins. That would greatly change the perception of what Ole is trying to do. But when 2 of your front 4 come from Pereira, Mata and Lingard every game, you're fighting an uphill battle.
