Yes, but they had the opposite effect. Which is getting quite normal. I've said it elsewhere, I'm still on the fence with him, but he doesn't navigate this media part of the job well. He says "we're Man United and we have to win every game" while at the same time he acknowledges that Rangnick was right. He'd have been better served (hindsight) to have endorsed Rangnick's take in part, or at least sat down with him when he joined.
With Ugarte he could have just said it'll take him time to get up to speed with the minimal amount of training with the group, and that would have been fine. But he went a bit dramatic, which he likely did not intend.
