I think it runs much deeper than just that, I have a feeling Ashworth had started to embrace the woman and all age groups at youth level, all youth teams play 4231 or 433, players were being developed by the Academy Director; Nick Cox, and Dan Ashworth clearly liked ETH has he fought for him to stay and he’s a big fan of the English youth system for obvious reasons. Ashworth also recruited Christian Vivel as interim recruitment director, but he was previously technical director of Chelsea,
Vivell recruited S Kone, it’s clear that Berrada and Wilcox saw things very differently from Ashworth and they probably started to move Vivel to their thought process by saying Ashworth was a dinosaur and wanted Gareth Southgate or Graham Potter, as coach,
Wilcox now assuming most of Ashworth role , charged Vivell with recruiting young players to suit Amorim’s 3421 system as Wilcox assumed more of the DOF role
Jason Wilcox is an elite youth operator and recruiting specialist, especially with British talent, he probably had very different ideas to Ashworth. I think the main problem with recruiting Ruben Amorim, that both football experts at the time, Wilcox and Ashworth were told by Berrada, Brailsford and SJR that they would be appointing a young PL unproven coach because they were convinced he was the next big thing and they had very little say in opposing the idea.
Jason Wilcox went with the flow and Dan Ashworth vehemently disagreed because he was thinking about the whole club structure.
Ruben been here 3 months won 9 drawn 3 lost 8, been incredibly average to poor but look up the under 18 and under 21 recent formations and your see they don’t play Ruben’s 3421 system but instead 433 or 4231, that in its own right shows the issues the club still has internally that Ashworth tried to resolve but was pushed aside.
