MGW and Reinjders together with 2 full backs are the logical choice. We have seen this season so many mistakes from these positions resulting in very sloppy goals. I would have preferred FBs from the prem but even then there isn't any guarentee they will easily adjust to Pep's requirements so we will just have to see. Back up to the new FBs can still be Nunes/ Ake and that's pretty good so overall the defence would be in a strong postion.
MGW and Reinjders provide goals from the midfield, are good technical players and young enough still to press, they are a very good fit for our requirements. We will still have Silva, Gundogan, Gonzalez, Rodri and kids to fill the midfield (Wirtz is a great player but alas not for us). We have had calls all season to give kids a chance so maybe we are with Echeverri and Bobb as AMs as part of the squad. Saying all of this if we could Wharton as well I'd be overjoyed.
Including replacing a GK then that's 5 incomings and outgoings potentailly of Ederson, Walker, Stones, Phillips, Kev, Kovacic, Grealish, McAtee, other kids means our DOFs are going to be very busy and we can only do so much
