Quite frankly if he was sacked now I wouldn't complain. With the quality of the team we have we should at the very least be in the play-offs at this stage of the season.
However, I would personally give him one absolute final chance.
Our next game is Brighton at home. I think I'm right in saying they have only won one league game since August, I would let him have the international break to regroup and rethink things. I was one of many Norwich fans that was disappointed when he was put in charge, and was very critical of his decision making throughout yesterday's game, however I don't feel that this poor run is all completely down to him. Right at the start of this bad streak of form we played Charlton and Rotherham in successive games. Everyone knows what happened, a mixture of brilliant goalkeeping from the opposition and awful luck effectively lost us 5 points. If we had have got those 5 points then not only would be in at least 4th right now, we would never have gone on this dreadful run, and we'd probably be well clear at the top of the table. Yes this poor run is mainly down to Adams, there's no denying that, but had we had that little bit of luck then we wouldn't be in this position at all. Obviously the fact is that that's what happens in football, but that isn't Adams fault.
It's also still pretty tight at the top of the table. We may be all the way down in 10th, but we're only 6 points off first place Derby. Our next 3 games are at home to Brighton and Reading, and away to Wigan. Win all 3 of them like we should be doing and we'll be in 3rd/4th, plus we'll be in good form.
That's why I would personally give him one more game. If we don't beat Brighton, then fine get rid. If we beat Brighton and then don't beat Reading then fine, get rid, but my point is I would sack him quite yet.
I'll therefore save my vote until after the Brighton game. As I said, if Adams get sacked tonight then I won't complain, if anything I'd be pleased, but if it was me I would give him one final chance.
