The only thing United are doing during its "own process" is trying to figure out a way minimize the backlash from his return, otherwise no "own process" would be needed. He is already back on their website listed as a player for them, they literally couldnt even wait on hour. If they come up with a story thats good enough for half the fanbase, he stays and protests that will be massive at first will get smaller and smaller the longer time has past. My guess is that he will return to the start of preseason in the summer. They will choose the "he is a victim of false accusations after an argument with his loved one who said some things because she was mad at him" approach. Point out that they are still together (if whats being rumored is true) and that he has not been charged with anything. Then decline to ever comment on the matter again. Former The Sun Chief Football Reporter and now United PR adviser Neil Ashton will tell club journos what to write, Neville will sell the narrative about that "the young boy has not even been charged with anything and deserves a chance" on Sky.
Only way they would actually do the right thing and boot him out is if they fear it would cause a massive backlash from sponsors. Which is not completely ruled out, we all saw the pictures and heard the tapes. But considering what a disgusting club the rags are in every way, my guess is that he will play for them next season.
