Interesting discussion. Assuming we get in Ederson & Mateus F, it's likely we see option 2 discussed in the vid, with Carrick trying to maximize their strengths. With the increased games, we definitely need a good rotation and I hope Carrick can find that balance. Mount definitely needs more game time, and I hope Bruno understands the need to conserve his efforts, not necessarily starting every game.
Concerning RM and their transfers, we might not get Tchouameni, but Camavinga or even better Chema might be CM#3. Mou is not a fan of youngsters when he has in-prime players, so if Rodri or Enzo do make the switch, I can see at least on of them being available. For the price of a Baleba, we'd get a more creative & technical player in Chema (or even Cama). Tchouameni is probably a bridge too far, but figure RM-related transfers will be late in the window.
