I doubt we will see Valencia in the starting lineup again. Maybe in the FA Cup but not this year - and even then, Dalot may be fit enough to play, so unless Shaw picks up another injury or Darmian leaves we will be okay in depth until the summer. I think Mourinho has reached his limit with Valencia in a similar manner he did with Jones. With Valencia's leg problems he's only been able to play one game a week and has played about a third of our games due to a couple of injuries he picked up. Valencia and Darmian will probably both leave by the summer, Young will probably be offered a one year contract and we'll sign another RB and LB. If Shaw, Dalot and the two new fullbacks are fine in term of fitness by the end of 2020 then I think that'll be the end of Young's time here.
