1. Insufficient Investment: Over the past decade, Arsenal have invested nearly £50 million less in player acquisitions compared to their Saturday opponents, Sunderland. However, unlike the Black Cats, Wenger's team has consistently been in the top four of the league rankings. Earlier, they were one of the two major powerhouses alongside Manchester United, but the subsequent involvement of Abramovich and Mansour changed the landscape of the Premier League. In today's money-driven world, lack of investment is tantamount to suicide. Arsenal can be seen as having attempted suicide multiple times without success.
The question is, knowing this, why do Arsenal's management continue to allow it to happen? Wenger firmly believes in his transfer strategy, which can be summarized as "only buy good players, not expensive ones." In Wenger's view, a player who could prompt him to write a check for £15-20 million is certainly no ordinary talent, and a weekly wage of £100,000 is an almost divine treatment that even Van Persie doesn't deserve.
Kroenke said: "If you start with big spending, this pattern will go on endlessly. No amount of money can solve fundamental problems." But it feels like Arsenal is trying to justify itself.
Clearly, Wenger's or Arsenal's previous policies have gradually been phased out by the current football world. To regain dominance, perhaps more investment should be considered.
