Isn't it awesome?
Let's differentiate between disappointment and nonsense. No one expects Grady Little huckleberry happytalk when your club loses. What is annoying as f*** is listening to moaning about a cheap owner when the club dropped £44M and huge wages on three world-class players over the summer. I don't care if everyone knows that Kroenke is cheap; that's not what the facts say. There isn't a single club in England, outside of maybe Man U, which had a specific need, that wouldn't have taken that transfer haul over what they brought in. But the results are bad and everyone knows that Arsenal are cheap, so that's what people moan about.
At the risk of being castigated for defending the Arsenal fans on the board, out of the bigger clubs (Arsenal, ManC, ManU, Spurs, Chelsea) they are the only one to sell players at a profit
the last 6 season in total (including this year), and 4 of the last 6 seasons individually. (I'm going with 6 years because that's when Kroenke became involved.) Certainly in comparison to those clubs, calling Arsenal cheap isn't unfair. They've also been great at deriving revenue through player development, but we're in an era where running a deficit in player acquisition is the more reliable way to the top of the table.
It's great for the books, but not great for competitiveness. Just because they are repetitive in saying the team is cheap doesn't mean it isn't true (Although I'd use thrifty, as they do unearth some gems), and I wouldn't begrudge them for wanting their team to spend like others. Sox fans were a lot happier once the spending deficit wrt the Yankees shrank.
We can't look at buying players in vacuum, no matter what the order. They ran a £12m profit in the transfer window last summer. Teams go into the window with a gameplan - Van Persie had a foot out the door, and Song was at best 50/50 to stay, signing Ross/Napoli means Salty is expendable, etc. If the Cs sign some FAs then trade a solid guy with picks for expiring contracts to get under the cap, you can't say "look at all the guys we got!" without thinking about the guy/picks we let go.
