The success of Brighton and especially Brentford is the clearest possible evidence that analytics works, as both clubs have owners whose business is data analytics. And the analytics stuff is only a part of the process. They will mine information on players from as many sources as possible, including, I kid you not, football forums. The truth is it's not going away. In fact with AI it's only going to become a bigger part of recruitment.
I get why people dislike it so much, because it takes the game away from its roots, and ordinary supporters. But claiming it doesn't work is pure denial.
