OK, if it's not a disruptive player, and it's not the wages, then I'm a bit stumped. What "disruptive thing" might have happened in the first four games of the season, that also happened recently, but didn't happen in the rest of the season?
A few wild stabs, all highly unlikely, except possibly 4):
1) The Prince has his favourites, and has been insisting on having a say in team tactics or selection - and threatening to disinvest if his demands aren't met (very unlikely)
2) McCabe has been showing up in the dressing room to give impromptu team talks that do more harm than good (highly unlikely)
3) Wilder is suffering from some form of recurring ailment or illness that prevents him from being fully "on the ball" in the dressing room (very unlikely - even if it were the case Knill is more than capable)
4) Someone in the first team is screwing someone else's wife - it was supposedly sorted out early in the season, but recently it was discovered that it's still going on.
Any of these close?
