Managers shouldn't be involved in these kinds of decisions and it's unlikely Fergie/Mancini etc are. Leave ticket pricing to the marketing department.
Our ticket price increase was a real own goal by the club given that it brought in only around 4.5M and we made a 18M profit on transfers this season. We already had the highest prices in the league IIRC and raising them does nothing apart from piss off fans, a lot of whom are already on the fence about attending games.
So you think they are not told and its just sprung on them?
