I note this about data-driven recruitment from Ally Gold's discussion with a Midlands football journo, "former Aston Villa correspondent Ashley Preece", about Lange's time at Villa.
-----------------------
Gold: You need to have a strong personality to succeed at Spurs, will he [Lange] be able to hold his own within their set-up?
Preece: He'll have to but Lange is softly-spoken and doesn't rock the boat too much. He worked well with Dean Smith who was used to working with a sporting director. However, under Steven Gerrard, it was different. I got the feeling the two never saw eye to eye. Gerrard would often say how 'all the numbers would blow his head' in terms of the data for players. I remember Gerrard saying how much Villa were 'data mad' in reference to Lange's way of working. Gerrard didn't really get Lange and cracked on making his own signings: Coutinho, Digne etc.
------------------------------------
I doubt Ange will go full Stevie G about a data-driven approach. Also, the Coutinho signing was pretty disastrous given the money involved.
But I imagine, as a straight-talking Aussie & highly experienced football coach, Ange will not allow himself to be blinded by numbers either.
I saw some comments where Ange talked about watching videos of matches played by our returning players - like Udogie & presumably the likes of Gil - whilst they were out on loan last season.
I'm sure he'll want an eye test to complement the underlying data about any potential signing.
He's also shown that when players have a skillset he likes, he's committed to developing them. Eg coaching the likes of Porro & Udgogie to play as inverted FBs, which neither of them have done before in their footballing careers.
