Well when Moreno or Digne advance, Foyth in particular would be a good addition to a back three that forms. Something Young does but Cash isn't as strong to hold back.
The right back needs to keep good shape as Digne and Moreno marauder forward. According to how I see it tactically, this explains why Young has been frequently preferred ever since working on things during the world cup break. The defender first and foremost is concerned with positioning and reading the play. .
In that capacity, Young is more disciplined than Cash in able to hang back . Emery system sees Cash vulnerability occur more with a concern if he loses a ball upfield and then failing in defensive transitions. Seems Emery doesn't want that risk.
We all saw Cashy's strength in winning the ball from Zinchenko and quickly and accurately passing the ball to Watkins this was a great assist for the goal. That's a good quality and he shows good ability there but its the overall ability as a right back for Unai Emery strategy that could and does find him wanting.
We also all saw his inability to read the danger for the fourth goal and prevent it from happening. As a result, when the ball was turned over from the corner in transition, Cashy was unable to prevent the opposition from scoring.
It all comes down to balance in playing as a right back for Emery. Villa would ideally have a combination of Young and Cash in one player.
I think if he can understand how his role is both defensively and in and out of possession then hope for Cash but it's about developing his understanding in playing that role and ability in possession.
I have him as an ongoing concern and highlighted other international right backs Emery has worked with that would be able to perfom to a more efficient ability or offer competition in the squad in that position.
