Because it flatters their egos, to present the idea that they actually know more about the club - and it's not just as simple as Daniel Levy being a tightfisted prick. Ooooooooh no, that's faaaaaar too simplistic and simply must be dismissed with an needlessly patronising tone.
I find it hilarious that the blame for not sourcing a striker was - at one piont in time - laid at the feet of Redknapp. Apparently he was clueless, no plan, no direction, no perception of where the team was weak. All hail AVB - he'll see it; he's the messiah - he'll bring us our wonderful striker!
Nah, no fudging striker. Change of manager, but no fudging striker. Guess what, who's the ever-present?
KNOCK! KNOCK! Yep, it's Daniel Levy girls and boys.
Because you know what's happening and know that Levy has deliberately screwed up signing a striker several times?
