Sometimes I wonder if scouting in general is a defunct industry. Full time scouting, anyway.
Clubs have part time regional scouts who watch games and report back. My assumption is they will do the same thing for a number of clubs and go with a brief in mind to look for certain things for a certain team, or watch players on a tip off from someone else before recommending them to someone next in line. The same thing with youth teams and district/county trial matches.
Pushy agents tout their client around from club to club, arrange trial trips to a country and a week at various clubs to get him a move. More of these and there is no need for scouts to go anywhere, the players come to you.
On top of that there are independent companies who compile footage of players and send the DVDs to clubs. My friend used to do this for the Belgian and French leagues, Spurs was an occasional client although I don't know who they were looking at - if anyone. It may have been potential Europa/CL opponents.
No doubt games like Football Manager have been used by teams, maybe not to sign someone based on a 20 season game as Spurs manager but as a guide to research further into the player. England has a problem whereby Brazilians or Argentinians have a language barrier (although they seem happy to go to Ru$$ia for a while) and a visa issue to overcome, as well as the common third-party ownership outlawed by the PL. It does mean losing out on talents to other leagues or having to delay signings of prospects for a year or so where a lot can change - injury, ownership %, development.
So many games are televised, if you go to the popular streaming sites you will see games from all over the world at all levels. There are very few players that are 'unknown' to clubs, but buying them is getting harder and harder.
There is a scene in the Moneyball movie where the old baseball scouts sit around with Brad Pitt and Jonah Hill pleading their case and justifying their job.. stats can't see what we see, they don't have the judgment that we have, etc etc. Maybe but judgment is wrong as well, all signings are a risk. High performing players in low performing teams represent value and are worth following up, watching a game in isolation doesn't show that either. Wenger was tipped off about Vermaelen and sent his scouts to watch him so many times, often when he was a full back. The scouts said he was average or worse. Then they went back and saw him play at centre back and he was much better. If it was just on scouting they wouldn't have signed him.
I think what is more important than scouting now is having good relationships with clubs. As the wealth becomes concentrated at the top there will be others who need to sell year on year, being top of the list when chairmen need to make a call is valuable. Maybe more valuable than sending someone off to watch a game on a Saturday or Wednesday night.
Also, developing the recruitment network for the academy. Actual talent rather than just size and strength. Getting the prospects first, seeing things in a kid that others don't. This can be done through the schools I suppose.. no doubt Spurs do all these things, I just think the expectation placed upon a scouting network is more than it should be and the thinking is outdated.
