I have no idea why you are so strict with players positions. There is a difference between DM and CM but dividing players into LCMs and RCMs? Players dont become worse if they get moved a little to left/right, they still have the same role to play. So its Marchisio, Lemina, Diawara at DM and Pogba, Khedira, Marchisio, Lemina, Sturaro, Diawara, Padoin at CM (in case Pereyra, Hernanes and Asamoah leave). And Sturaro is what, 6th choice midfielder? Wed have to have a serious injury crisis for him to start a run of games. Our starting trio is Marchisio-Pogba-Khedira, then Lemina as 1st choice from the bench (can play both DM and CM effectively), then comes Sturaro but would probably be overtaken by Diawara soon enough in the pecking order if we sign him. If Evra leaves we will ofcourse sign a replacement. Counting on Padoin as the only sub for Sandro would be unwise.
Well see what happens, id love Asamoah to be given a chance to regain fitness and return to the form he had under Conte, but I doubt that will happen, if we intend to sign a new CM in the summer
