From memory (which admittedly isn't great) I seem to remember that Seville ended up fighting fire with fire.
My feeling was that Anthony Taylor, rightly or wrongly, had seen Mourinho teams and their antics before and some decisions may well have gone against Roma for that reason and not on merit.
I for one was glad that Roma lost and thought Taylor had an unusually good game, though I may have been as blinkered as he :hehe
I also remember that neither Jose nor any of the Roma staff were very gracious in defeat.
