There's a stat going around too that our defensive line dropped significantly when he came into the team too, which impacts how compact the side can be. I think our press was suffering because of that, Partey seemed to have to cover acres of space at times.
Holding isn't actually a bad defender and it's not really his fault, he's just not suited for our current style of play. It puts a huge demand on his biggest flaws (lack of pace, having to cover big spaces, not liking people running at him, passing under pressure). As much as it sounds like scapegoating, I think it's pretty obvious it impacts players around him too.
