We'd strengthened the squad in the summer - what was needed was to strengthen the team. No point in buying players just to fill up the 25 man squad if they're no better (or even as good) as what we'd already got. Anyway, we can only pick 11 for the team, with 7 on the bench, so more than a quarter of the squad isn't even involved in the match day; 23 players - plus youngsters - is plenty to choose from.
In one way, Potter's arrival has changed nothing - we still need to buy quality players to improve the first team now, not to flesh out the squad with bodies.
