I thought from the start that you could tell by his body language that he believes every word that comes out of his mouth. Ole is a man shaped by United and for many things, there is only one right answer. For him, United is a way of life, and it defines how you do things. No doubt, if a player isn't buying in, he'll be shipping out. His first goal coming in seems to have been getting everyone on or off board. Looks like almost everyone is buying. I swear, these guys would smash into a brick wall for him.
As for his tactics, it just took him this long to figure out what he had to work with. And with Bailly as an example, he's still experimenting. I don't look at that situation last night as a tactical error so much as a tactical decision that didn't work because Bailly simply couldn't do it. Difference being, a tactical error wouldn't have worked no matter who you put in. And I agree, you're spot on, that Ole is adaptable to the situation.
They really need to get the permanent deal done so the press will quit asking the same questions every interview. That said, I'm pretty sure he already has the deal. He's made enough comments that tell me he's hiding something. He's answering those questions almost too easily, too casually. Good answers, but his delivery is... different... when he gives them.
