I didn't say they didn't watch games. That's how they collect stats. But that's all they're doing - collecting stats. Most anyone could do that. They're not doing the really important work, which is working out if and how a certain player will improve our team. That's where the real scouting talent like Walsh comes in.
Wrigglesworth only joined the club in a full time capacity in July 2013. He started as a technical scout and that was his first job after graduating with a degree in Sports Coaching from Leeds Met. We had already signed Anthony Knockaert as well as players like Danny Drinkwater and Matty James before he even started working for the club. He became head of technical scouting in March last year, so had only been in the role 9 months before he left in December. With all that in mind, I find it hard to believe he was instrumental in setting up anything, indeed he makes no such claims on his linkedin profile or in any interviews. His new role at Arsenal is simply called 'First Team Video Scout', which would be a hell of a step down if he really was instrumental in creating our entire international scouting network. Clearly he wasn't.
For your info, the new head of technical scouting is Ollie Waldren, who is more experienced than Wrigglesworth having began working as a football analyst in 2009.
I suggest you have a browse through the hundreds of 'technical scout' or 'football analyst' profiles on LinkedIn. This will give you a more realistic picture of what these types of roles actually involve. It's very simple stuff, just using modern technology. We're not unique in using these type of people, every club has them. Man Utd's senior performance analyst, Paul Brand, started his football career as Blackburn's Head of Performance Analysis. Immediately prior to that he was a shift manager at McDonalds. To be clear, he went from working in McDonalds straight to being the Head of Performance Analysis at a major professional football club. That should tell you everything you need to know about how much talent is required to get those kind of jobs and what value is placed on them.
