As pretty much everyone has access to the same data these days, the big issue is how you interpret and use it. When Ashton was here, it does seem that the bloke that loved to wheel and deal was given the scope to buy players. Absolute car crash scenario.
When Brentford let Warburton go and move towards a "moneyball" style recruitment, I thought they were mad. But it all comes down to how you use what you have, and they've done brilliantly . What Brighton, Brentford and lately even Fulham have done is , pick a shape/style/identity call it what you like, but then all incomers have to fit into that system. That is from top to bottom. It feels with Nige taking interest in the youngsters and having a hand shaping recruitment, we are moving more towards that thinking.
