I'd love to stick with 4-2-3-1 but I'd be amazed if we played Dusan as a 10 again because that's basically leaving the midfield wide open and going mano a mano, which is great (and refreshing) against Sunderland, maybe not against United as that's probably their strength and they'd kill us on the counter eventually. Then again maybe with a week and a half of prep Dusan can be drilled into man-marking Herrera. I'd be very surprised if we don't just play 4-3-3 with the same personnel, maybe a compromise would be Davis or JWP playing as the 10 but I'm not sure. As long as we keep our midfield narrow so we can play through it quickly I'll be fine with 4-3-3, I'd rather us not have our lengthy transition in shape where the CMs split out once we have possession.
