But he's a technical scout ... elsewhere.
With respect, you don't know what you're talking about.
Our 'technical' scouts watch loads of matches live each every year. They travel every bit as much as any of our actual scouts. So for example, both McKenzie and Wrigglesworth went to watch Mahrez on numerous occasions.
We subscribe to a data package that Rob McKenzie, Ben Wrigglesworth and others then developed and developed over a period of years to shortcut our need to do actual scouting. At the time, we lacked the network to be able to travel the world watching players and so wanted a way to find players more efficiently.
Our technical scouts have a database of hundreds of potential targets that changes all the time. They constantly watch players live on that database as well as on video in order to evolve it. When the club want a particular position strengthened, or we find someone we think may be worth looking at further, David Mills and his team look and then Steve Walsh does too.
This is a well refined and proven process that is absolutely vital to our 'edge' over our competitors.
My point in my previous comment in this thread was that the two people instrumental in developing this approach are no longer here. Instead, they are at rival clubs having taken everything they've learnt with them. I have no idea whether there is anything in place to stop someone from taking our 'list' of targets with them, but I doubt that it is feasible to do.
Now I know Steve Walsh is the key man as he can 'see' the potential in a player that distinguishes him from many other jobbing scouts. His track record is outstanding. This is why Arsenal want him too and I'm sure we'll have a hell of a job retaining him in the summer.
But anyone suggesting that losing key members of this team is anything other than seriously damaging to its effectiveness is deluding themselves. I don't know who is replacing Wrigglesworth. For all I know, he may be better. But it does matter.
