Slight difference of between our loss to Chelsea and theirs, was that ours was the very first PL game for our manager and a just promoted championship team. It's incredibly bad to suggest that what Lambert doesn't know what he's doing, but it's also bad to think the plans very good in the first place. It's a young team and with youth comes inexperience and inconsistency while at the same time he's got some good players with plenty of experience of the PL and in reality he is falling incredibly (almost embarrassingly) short of where that club should be aiming. You could say this is a year of transition..... well this was supposed to be our year of transition and we are media darlings at the moment. Chelsea are supposed to be in a year of transition and are being tipped to compete for the title.
Fact of the matter is this season has become about damage limitation and it's not exactly working at the moment. Lambert won't have that time to work if they slip from this league which if they lose to Wigan could begin to become a possibility.
You make some valid points however I don't believe we were ever a team in transition as we only made subtle changes to our squad, we simply took a punt on an unproven head coach/manager but no I don't believe were in transition. As for our brilliant season so far this I'm honestly not surprised by it too much, I genuinely believe we are in the top 6/7 teams in the country and our quality of player and performance warrant our spot.
Villa have made massive wholesale changes to their squad whilst also appointing a new manager so as you point out are definitely in a period of transition.
After a pretty horrible start they have slowly but surely got better which peaked at Liverpool when they swept away an admittedly poor Liverpool side. They have been bashed up by the European champions and a top 4 side who have the best player in the premier league on his day.
My feeling is they will definitely compete with the sides around them and take sufficient points to stay up quite comfortably and next season Lambert will be given some decent cash, from the inevitable sales Bent and 1 or 2 others, when they will kick on and challenge us for the top midlands side.
Hope you're right and I'm wrong but I severely doubt it.
