I've posted earlier that IMO the failure to replace DD played a significant role in the demise of AW and the club. Thinking purely in terms of the football on the pitch IMO AW lost it when he tried to apply his 'player intuition' style when utilising players who were still learning their game and roles.
I have no issue with a decision to retain the style provided that the team and players were fit for purpose. But I dispute that you can do so effectively with players who are still learning and developing, and yet are not being told what they need to know or do. As such IMO the twin aspects of 'player intuition' with developing players meant that both aspects would always be poor bedfellows, particularly as AW also said that a player is not fully developed and able to play with any level of performance or consistency until aged 23.
I also think that this is also the reason as to why so many development players have stagnated and regressed once they break through to become an established part of the senior match day squad.
I understand the arguments for utilising the development players with the self imposed financial restrictions, but IMO that argument becomes invalid when we continually generated season profits and then didn't directly reinvest into the playing group other than wages, and then wiped the slate clean to start from scratch the following season.
Further to this IMO it all became a bit self indulgent on AW's part post the Fabregas era with the rebuilds post 2010, and even more so once we had the new commercial revenues in the Ozil era. During this time AW repeatedly threw out the baby (player) whilst keeping the bath water (style).
The failure to spend what revenues he had in order to build a team that was fit for purpose was highlighted when he chose not to sign any outfield players the season when the new TV revenues kicked in, with most clubs choosing to invest in their squads ahead of the new revenues coming to hand so as to improve their table position and their revenue as a result.
In many ways the more freedom AW had in terms of control and finances the more entrenched he became in his determination to stay true to his principles. As such I wonder if part of his 'bitterness' with the supporters is that he cannot understand as to why so many do not share his values and beliefs.
