Good post and valid points well made. I just want to address the question you asked about why these players haven't improved or left. As I've said earlier, part of the reason why Wenger still keeps his faith in these players is his emotional attachment to some of them. As he's bought or nurtured a lot of these players from a young age, and he's clearly seen something in them to show that they could make it at Arsenal, he's tried to stick by them through thick and thin because he doesn't want their careers to be wasted playing at a level he deems to be below what they're capable of. This is where you need to be ruthless and take the hit on some players because, regardless of how good they may have looked before, if they're not cutting it, they're not cutting it and you need to accept that for whatever reason it just didn't work out. Which brings me onto my next point - Wenger's ego and stubbornness. I genuinely think that another part of the reason why he's kept these players is because he wanted to prove a point that you can win the league through acquiring or developing players when they're young and turning them into top class players who can compete. His youth project has been a failure, but I feel like he is still reluctant to accept this and still won't let go of some of these players in the faint hope that they will one day finally come good. Part of it is down to proving the media and pundits wrong who have ever doubted him and questioned his tactics. He seems to make it his personal mission to prove that he knows better than the rest, so part of the reason he holds onto to these underperforming players is because he also doesn't want to concede that his purist methods and ideas won't come to fruition. But it's a tricky one because part of the reason for these players' regression/stagnation is down to Wenger himself - so if he got rid of these players and brought in new ones, would we really improve that much? Because it just seems that no matter what player we bring in or how varied our team looks, we suffer from the same problems every year - and that, undeniably, is down to the manager. So due to Wenger's flaws, I'm not so sure we'd even be performing significantly better than we are now even with better players because I don't think he'd know how to maximise their potential.
