As Arsenal continue to lead the way at the top of the Premier League table, some have argued that their success is simply the product of good luck. Detractors say that the Gunners have been fortunate with injuries - the four-month absence of Gabriel Jesus notwithstanding - while last-gasp wins against Aston Villa and Bournemouth have only served to fuel this fire.
The argument has now extended into their business in the transfer window. It's no secret that Arsenal wanted Mykhailo Mudryk and Moises Caicedo last month, but ended up with Leandro Trossard and Jorginho instead. While their initial targets have gone on to slightly underwhelm since January, the signings Arsenal actually made have already made significant contributions to their title push.
But having transformed Mikel Arteta's squad from failing to qualify for Europe to title contenders in the space of four windows, the Gunners' transfer hot streak cannot just simply be cast aside as good fortune. While other Premier League sides have indulged in the madness of the transfer market, Arsenal have a clear method.
