From all the midfielders that moved this summer across the PL, I bet no more than 1 player betters Xhaka's 14 g/a from midfield last season. Albeit, playing 6 games more, Xhaka had better numbers from midfield than Gundogan.
Rice is better than Havertz to partner Partey and gives us far more defensively, but he's not going to score or assist many goals.
