GK
de Gea
Henderson - Odd league game, Europe, FA Cup
Romero - League Cup
RB
Wan-Bissaka - Should start in all games other than bad fixture pile-ups
Dalot - Should push for a starting spot, first one in at RB and LB
Laird/O'Connor - In the event of injury/fatigue of AWB + Dalot
Young - If everyone else is injured
LB
Shaw - Same as Wan Bissaka minus League Cup
Dalot - As above with added League Cup
Brandon Williams - Checkatrade Trophy, in the event of bad injuries.
CB
Tuanzebe - Start wherever possible and persevere.
Lindelöf/Bailly - Should rotate and push each other for the other CB spot.
Smalling/Jones - Only in the event of injury.
Rojo -
DM
Matic - I know, but he can be useful if he is fit and used in a sensible squad rotation.
McTominay - League games to rest Matic, FA Cup and Europa
Garner - League Cup, Checkatrade
CM's
Fred - Our best central midfielder. Must start.
McTominay - Can start here when he needs too.
Lingard - Capable in CM, probably his best position given his general lack of end product
Pereira - New Contract has been given, now he needs to play up to it.
Gomes - FA and League Cups, Europa, Checkatrade starts. No question
Mata - Reckon he can be used as an LCM, if Pogba goes I reckon he stands to benefit the most. We will play with a definite double pivot more and he will occupy the 10 position.
RF
Greenwood - Start him wherever possible in the league, needs workload managed owing to some niggles.
Lingard - An option here in bigger games.
Chong - Play whenever Greenwood can't in the League, League Cup, Checkatrade, rotate Europa and Fa Cup games with Greenwood
Dalot - Another option for him to get game time
CF
Rashford - Just start him through the middle now and let him develop.
Martial - First reserve in if Rashford is injured
Greenwood - If neither are available to play upfront
LF
Martial - All league and Europa
James - First up if Martial isn't playing here for whatever reason, FA Cup and League cup also
Greenwood - Another way to get him minutes.
