flobaba -- I think Timber has clearly shown the "levels" by over performing in areas that aren't White's strengths. In particular, we see in Timber a player more comfortable attacking and in defending faster/trickier wingers.
Now the question for Arteta and Timber, and Saka, is can they get the balance right so that a more attacking fullback doesn't jeopardize Saka's role in the team. I've had plenty of time and love for White as he - much like Sagna - has afforded the winger ahead of him some extra freedom in attacking/positioning/defending.
