He's a really good player, and his output this season has been decent, but maybe it just doesn't work and we should accept that.
I think it was fair for Silva to try to make our midfield work with the options we have, because we do have good players and it was reasonable to try it, but the balance never seems to really work properly.
So maybe it's better looking at his team like a construction job, and maybe the best move he can make it just to rip the midfield out altogether and build it as you want it, rather than trying to refine an imperfect set-up.
