1. Insufficient Investment: Over the past decade, Arsenal have invested nearly £50 million less in player acquisitions compared to their opponent on Saturday, Sunderland. However, unlike the Black Cats, Wenger's team has consistently been in the top four of the league table. Earlier, they were one of the two major powers along with Manchester United, but the subsequent joining of Abramovich and Mansour changed the landscape of the Premier League. In today's money-driven world, not investing is tantamount to suicide. Arsenal could be seen as having attempted suicide multiple times without success.
The question is, knowing this, why do Arsenal's upper management still allow it to happen? Wenger firmly believes in his transfer strategy, which can be summarized as "only buy the good ones, not the expensive ones." In Wenger's view, a player who can make him write a check for £15-20 million is definitely no ordinary talent, and a weekly salary of £100,000 is a godly treatment that even Van Persie doesn't deserve.
Kroenke said: "If you start with big spending, this mode will never end. No matter how much money, it cannot solve substantive problems." But it somehow feels like Arsenal is justifying itself.
Clearly, Wenger's or Arsenal's previous policies have gradually been eliminated by the modern football world. To revive its former glory, perhaps it should consider increasing investment.
