if you want the attention of someone at that level, writing a letter like that is not the way to do it, and in the highly unlikely event that that letter ever made it to his desk, he would get 2 lines in and throw it away.
He wouldn't tolerate anyone talking to him like that.
Mail sent to him for business would be opened by a PA and that would be filtered out at that level. No PA worth their salt would ever present their boss with something like that.
The intentions of the letter are fine (ish) but the method and delivery are niave and crass and would not be entertained by someone who operates at his level.
If you believe that in 20 years of running a top flight football club, that Daniel Levy has learned nothing about the game, the expectations of the fan base, the expectations of the media, the pressure of the media, the politics of football at national, european and international level as well as how to deal with political influence then you are a fool.
He may not be a die hard fan like you and me, but he knows more about the game than you or I will ever know.
we might know the names of the double winning team, or who took the penalties in the EUFA cup win and he doesn't, but he knows how to run a football club and keep it alive, and as he's proved, keep it dining at the top table. We might not get to take home the silverware but we get to eat with the people that do, and that means that he's doing his job well enough to sustain the clubs value.
But rest assured, he wants the club to win things, because it means it earns more money, he doesn't care about the kudos and bragging rights like we do, but he wants the success like we do.
Just for totally different reasons.
