Having to 'redesign' Pogba's role is another way of saying Ole was attempting to shoehorn both players into the team.
The transfer committee consisted of Bout, Lawlor and Court who is the Head of data analysis. And these are the same three guys who Daniel Taylor in 2018, said had vetoed Mourinho when he wanted to sign Maguire, Alderwereild, Boateng, Willian etc. Taylor finished of by saying that Maguire and Alderwereild were deemed not good enough to take United to a higher level by the people working on the football department. Woodward a year later went ahead and delivered Maguire for Ole, Phelan and their personal scout Simon Wells.
Ole's problem was that he couldn't really see past the most obvious signings imo. And according to reports, Ole kept telling Woodward to keep trying for Sancho until the end of the window. But it was Joel Glazer who brought the failed pursuit to a end, 3 weeks before the close of the window according to The Athletic. And with time running out in the window, you can only make panic signings or youth signings at that stage, so quantity over quality was the reality, because no club is going to want to sell their best players at short notice. Ole put all his eggs into the Sancho basket and it back fired.
