In fairness, though - at some point they have to come to terms with the fact they've, er, slipped down the ranks permanently. They have to get back to a position from which they can allow themselves to scoff at 4th place trophies or the sort of "progress" they're enjoying this season.
If it were true that Liverpool were genuine "champions elect" before the season, Barrett would've had a point. But they weren't, were they? Liverpool nearly winning the league last season was down to several factors. The club being back on top of the English game in terms of structure, finances, pulling power, having the best squad...and so forth - was not one of them.
Brenda has taken one more step as a manager this season in my opinion. He has been knocked down severely - and managed to get back up satisfactorily. That's an important lesson for him - and, yes, in the bigger picture of "general progress" this does matter IF Liverpool's plan is to stick with Brenda.
