From what little I know, I think this is a good hand. He is a very data-analytics driven man, came to Brentford in 2019-ish and helped produce such rapid progression in set pieces there that he was poached by Arteta, whose Arsenal was among the worst in the league in set pieces defensively and also going forward. He improved them immensively in defensice set oieces the first year, and also in defending crosses and similar in open play, but chose to take a head coach role promotion in his own city Malmö before he could do much about the attacking set pieces. Wilcox worked with him at Southampton in 2023, so should know him very well.
