He said: "I'm clearly disappointed with every aspect of the performance apart from Davide Grassi, who I think was the only player to show the commitment we require of them all.
"We're all playing for our futures. There have been certain aspects there's mitigation for and I don't feel culpable for, but when it starts to look like that then clearly I'm not getting as much out of the players I send out there as I require.
"That starts to reflect on me, so for the first time I'm starting to feel that I'm under threat. We have five games to go and require two wins, and that is starting to look like it'll be really hard."
McGhee was disappointed in the way his side lost their lead this afternoon, adding: "The goals are ludicrous. The first goal in particular was a joke. It was a blunder that I simply can't legislate for. I felt that our goal gave us an edge, so to find ourselves 2-1 down was ridiculous."
The attitude of his players was also bothering the Dons boss, who continued: "The players know they're not safe but they're just not showing the desire to do something about it. They seem to be hoping that something will happen elsewhere to see them safe without really earning it, and that's a worry for me."
