So you say sinking. That would imply going down the table. Except last season we finished 10th. Only 8 points from 4th and 6 points off 6th.
That was after finishing 12th the previous season (when the manager came in when we were only 4 points out of the relegation zone and in 15th, spent no money in the transfer window, but he was able to average 1.5 points per game for the rest of that season.) Take that over the whole season and he would have got 57 points and finished top 8.
The following season he did just that, and got 59 points but unfortunately, that only got 10th (would have got top 8 in all but 1 of the previous 20 years).
What he proved is that the squad is capable of getting points totals required for top 8. And actually would have done so, had it not been for Silva.
It's very disingenuous to act as if we are on a downward spiral, because on the pitch we haven't been, until this season. If he gets less points than last season, hell, less than 57, he has failed. Because this squad have shown they can do that.
