Connor doesn't count, everyone knows he was a stand in plugged in for the rest of the season given no-one else would come (we'd be in exactly the same position now btw if we sacked Lambert).
I didn't want Solbakken gone until after Luton and then we did the deed anyway. I'd have wanted him gone regardless - his position was obviously untenable - but in a 50:50 shout with him and Saunders I'd have retained Chromedome. That would apply with pretty much any manager tbf.
I think I gave Saunders two games before I'd completely had enough of him and I would have been happy for Zenga to go after Norwich, which was less than two months after his first game.
Solbakken had us 3rd in early October so I'm not sure how the "couple of months" timeframe could really apply to him.
