Can only assume he doesn’t trust Nknounkou or Kenny. Tbf Kenny looks atrocious.Too many changes to the back line needlessly.
Back four Niels, Kenny, Keane, Holgate, three in midfield Allan, Doucoure and possibly Davies then James in the 10 and Ritchie DCL up front.
Players in their best positions with what he has available. Changing the personnel in the back line every game is not going to help defensive stability, nor is have no two in midfield and a back five.
