Hold on! I'm just dusting down my "Five Pillars" handbook.
The Pillar states:
"The club aims to sign players aged 24 and under more often than not, with older recruits becoming an exception, rather than the norm. The club is also building up a database of young players in all positions to aid in talent identification."
The above statement is clearly ambiguous because "more often than not" suggests greater than 50% of the time. If we imagine the time-frame of this season than we could still get a few "exceptions" in without breaking the pillar. Also, the pillar doesn't stipulate whether "sign" means sign permanently or on loan.
Ultimately I think the pillar is probably shit and we should give up on it.
