we can probably get away with it with Digne because Benitez wants his full-backs to stay back unless there's a definite opportunity to get forward.In a team with relegation form, selling all the best players is not a good move. We will lose more money selling them now than we get for staying in the PL.
That being said, even with that factor and only having played 13 league games, Digne is still more creative than any of our squad bar Gray or Townsend (and per 90 mins played he's the most creative in the squad) and, this is the best part, even though he was taken off set-pieces after the Burnley game, he's still created the most chances from set-pieces!!!
