I mean I think the post above is quite literal evidence that Lazio didnt do it a couple of years ago.
I suspect a lot of it comes down to different coaching styles - and dont forget, it is a substantial investment. To do it for a first team you probably need 3 or 4 people full time reviewing videos, with the tactical knowledge, etc. That might be half a million a year, or more.
Its only in the last decade or so that you really start to see a lot of heavy analysis into it - and I dont just mean anecdotal stuff like AVB watching Newcastle for JM and providing an opposition report, but I'm talking about heavy statistical analysis on things like outswinging vs inswinging corners - I cant find the report off hand right now but it was like early 2010s that City actually used some data on analyzing what was more likely to score.
I'd bet a lot of this stuff (Being systematic rather than just opinionated by a specific scout) is still relatively recent.
I mean, fuck, Inter cant be THAT professional otherwise we wouldnt send players to mountain healers to fix their knees.
And like I've posted about before, kif you look at Klopp's top signings at Liverpool, basically all bar one or two have worked out for the club - the same is definitely NOT true at Inter.
