I'm not sacrificing foden, he's still miles better on the left than the right, he should always be starting on the left, he can press just as well from either side. He can whip in balls with his left foot like the chance Haaland hit the post with against Southampton.
Kdb finds himself out wide for a significant period when he plays in midfield, it's not a major change for him, gives him less responsibility defensively so we can have him higher up the pitch. we all know about his quality whipping in balls in behind. Against their high line its the easiest route through.
