Too early to characterise either side — these are the numbers so far, not a read on how they play.

Averages over the matches this snapshot has detail for — 2 for Sunderland, 2 for AZ Alkmaar. Too few to lean on heavily.

Goal involvements per 90, among players with at least 45% of the most-used player’s minutes. Drawn from the last 33 of 54 matches, not the full season.
