It's both the bare minimum and the loftiest aim.
In the 14 years prior to Ashley's purchase we spent 8 years in European competition (9 if you count Cup winners Cup, more if you count the Intertwobob), 8 top half finishes. Our lowest finish was 14th, our average points return was 59. Under Ashley our lowest PL finish is 18th, our average PL points return is 44 and we've been relegated twice. We're willfully standing still or declining while other clubs pass us by.
In Ashley's time, Brighton have climbed from 18th in League 1 to the Premier League, Leicester have gone from League 1 to consistent top half finishes in the top tier, Leeds certainly have similar ambitions.
And given both those players' injury record, wouldn't it make sense to bring in some back up? There's plenty of room in the wage budget to accommodate a sub striker/attacking mid, now that we've got rid of Muto, Lejeune, Carroll, Saivet et al. We didn't because Ashley's gambling on us having enough to stay up again.
Oh, by the way, ASM hasn't missed a minute of the Premier League this season.
History? How far back are we going? 14 years before Ashley? All time football league history?
