I disagree.
Against Swansea, around the 60th minute, some fans started to boo. Within seconds of that, a huge chant of 'Villa, Villa, Villa' drowned them out. 5-10 minutes later it happened again. A backpass to the keeper (or something equally irrelevant but somehow disgraceful) caused more boos, and again the Holte roared in their support, to cover the boos again.
That was my biggest indication, to date, that Lambert still has the majority on his side.
We were chanting, not to spur the players on, but to cover the boos and stop any loss of confidence that it could have caused to the team.
There are plenty of fans concerned at the goings on but who will never boo.... I'm one of them.
