For me you had 3 creative, defensively sound centre mids last year that also chipped in with goals. After letting Xhaka leave and buying Rice and Havertz, you have an absolute nothing of a second attacking midfielder to support Odegaard and you have a very good DM who has very, very little creativity to his attacking game.
With Odegaard it's not quite as good as last year, and without him it's quite a lot worse as he's the only creator assuming Rice plays ahead of Partey. Rice, Partey and Odegaard would be better than having Havertz in there for me, but it's still a bit pedestrian.
