I think the problem is that the rot is so slow that it will convince people it’s not happening

Since 2009, not been able to go through a league season losing less than 7 games
Since 2015, despite 15 attempts we haven’t been able to register an away victory at a top six side
Between 2011 and 2017, no matter who we were drawn with we couldn’t get into the 1/4 finals of the champions league
Haven’t won more than 14 out of 19 home games since 2010
Cannot challenge for the league without spectacular collapse February/March time since we last won it
