This is not specific to you rob, it's a general problem but this post and this mentality is a massive part of the issue football faces.
I've never known a group of people that want to have their cake and eat it quite like football supporters. The biggest complaint you see from football supporters, on here, twitter and pretty much everywhere else, is around transfer spend or the lack of it. Supporters constantly want more and more - it doesn't matter how much a club spends (see Utd supporters), they still haven't spent enough. And then we act shocked and offended when clubs put ticket prices up or broadcasters put subscription costs up or when clubs try to launch a super league or refuse to give money to the EFL.
We've helped create the monster that PL football has become and when we're really upset with the owners, we demand they sell-up and the alternative (we hope) is an Usmanov or some backwards state that decapitates people on a daily basis? Another individual, group or state that has no pure intentions and are only interested in exploiting the club and sport for their personal gain, whether that be financial or political.
I've seen Liverpool supporters call for FSG to sell-up after this, not me though. Nobody that's now willing or capable of buying the club will have any better intentions than FSG so why the desperation to jump out of the frying pan, into the fire? Particularly in our case where, on the whole, they've run the club incredibly well.
We've benefited hugely from allowing private ownership of our clubs but this set-up has risks (if clubs fell into the wrong hands) and the constant pressure from supporters on clubs to keep spending and spending has driven driven the relentless drive to create more and more revenue and led to vultures entering the game.
This 100%
Football fans for the most part moan about many aspects regarding the money, if they want a club to keep spending they have no right to then moan if ticket costs go up, shirts go up etc, if a club keeps spending and increases its wage budget continually they have to recoup the money somewhere, the easiest source for that is the fans. Similar if a club builds a new stadium or adds to it, that cost wont just get covered by sponsors and other means entirely. Take Spurs for example or us when we added to Anfield, the owners had improved it so if they wanted to they could have increased the ticket prices, ours tried but back down due to fan pressure.
John Barnes summed it up quite well in his TalkSport video, supporters and fans want all of the money to be spent, all of the world class players, whilst keeping it all as it is now which from a business point of view is impossible.
Regarding Arsenal if they sell and out of all the Top 6 it would be them id bet on being sold, i doubt it would suddenly mean you improve, weather Arsenal fans feel they have invested enough or not, the fact is they have signed players, at some stage players need to take more blame when they dont deliver, yet a supporters answer will always be "sell and buy more" when in reality it just isnt that easy or simple.
The rumour prior to that tweet was that it may of been us, however for the few mistakes FSG have made, I dont want them gone, over all they have done a very good job. They have expanded our reach as a club, invested in Anfield itself, re-invested money from players where as some owners dont even do that. They also brought us back from the brink of collapsing and our debt is long gone.
It wont ever happen but for me one way to fix the spending when it comes to transfers and wages would be to bring in a wage AND Transfer fee cap that all clubs of any league have to follow, however were at the stage now its impossible to do fairly.
