GK - not fussed
LB - An energetic, pacey attacking left back. Cucurella fits the mould, but just one example. He's also quite versatile and can fill various positions.
CB - ideally left footed, pacey, good in the air. Lower priority than other positions, so I'd be content with a young player who would be content to start on the bench initially, and ready to take their chances when our first choice are injured or out of form again with a view to becoming first choice. Salisu from Southampton looks good.
RB - complicated. Laird waiting in the wings but not ready, Williams potentially as a backup covering both flanks, Dalot and AWB both still young and have some potential, maybe, but a decison needs to be made, get rid of those the manager doesn't see potential in, bring in a quality RB, or another potential top talent like Livramento or Spence. I can see this being position being unchanged by the start of next season.
CM - Rice, Neves, De Jong, Tchouaméni, we need one of these at least. De Jong would be my preference, I love that style of player and its something United have lacked for several years, and ETH could build the midfield around him. Ideally two CMs, but I think one is likely with VdB being part of the squad, Fred and McTominay playing bit-part roles, possibly Garner in the squad, and possibly Hannibal although the latter may be used in more advanced positions. If one or two of the latter go out on loan, then maybe bring in one of the Ajax CMs or another youngster specialist DM for squad depth, with a view to phasing out McTominay the next summer.
AM - possibly the only place we're okay, with Bruno, backed up by VdB, Hannibal, Shoretire. The bigger question is whether we'll play with a number 10 most of the time, or whether we'll prefer a 6 and 2 8s.
LW - Another position we're OK in for a while. Sancho should be an important part of the new manager's plans, with Elanga and Rashford involved.
RW - We absolutely need a specialist in this position, not someone who can merely do a job there. Someone like Raphinha would be ideal but I don't think we'd get him, Antony maybe more realistic.
CF - If Ronaldo leaves we need a top number 9 worthy of leading the line for Manchester United. I fear we'll chase Kane all summer and be rejected, as we're currently a sideways/downward step from Spurs, and Kane doesn't seem to sort to jump ship for the money and he doesn't have time to wait a few years in the hope we become genuine title contenders. I reckon we'll see Bruno as a false 9 at times, perhaps with another 10/false 9 brought in too like Nkunku, and bring in another option who can play the traditional 9 role when needed. Ideally our new setup will identify a young player who can come in and provide competition immediately but has the potential to become top level, but I'm not aware of who and fear we'll end up with a short term backup option like Haller or Calvert-Lewin.
