Sacked Swansea boss Bob Bradley claims the club's owners "lost their nerve" and "didn't have the strength" to stick with him.
Bradley was dismissed after a paltry 11 matches in charge of the relegation-threatened Swans, during which the side were beaten seven times and conceded 29 goals.
The former United States manager's initial reaction to the decision was one of dignified calm but a clear frustration at the lack of patience he was afforded by American co-owners Jason Levien and Steve Kaplan emerged in an interview with ESPN FC.
In it, the 58-year-old said: "They lost their nerve. They reacted to the fans and didn't have the strength to see it through.
"That part I'm not happy about. I spoke very quickly to Jason Levien (after losing to West Ham on St Stephen's Day), I received a message from Steve Kaplan and both referenced something about 'unfair'.
"But you always tell your players that the game will challenge you in all sorts of ways. The game can be cruel. In order to have any chance you have to be strong. You have to believe in your work, you have to believe in how you do things as a group. It can't be thrown off track every time something goes against you."
Bradley expected to be given the chance to rebuild the side using the January transfer window but says such commitments were abandoned after the morale-sapping 4-1 home defeat to the Hammers.
"What I think happened is that (result) made everybody nervous," he said. "That loss and that feeling inside the Liberty that day meant that all the discussions and all the plans got thrown out of the window, and somebody needed to go. And let's face it, the way that works is the first one that's out is the manager.
"I'm disappointed that somehow, when a few games go against you, that all of a sudden all of those discussions and all of the ideas of what it was going to take to turn this around got pushed aside."
