The few players that are out for sure are Lingard, Pogba, I imagine Mata, Cavani and Phil Jones so that's 5.
Then you have likes of CR, Rashford, Henderson (GK) and van de Beek who depend on whether Ten Hag needs them.
Then some other dross like Bailly or Dalot to be binned off the wage bill too.
Then there's Greenwood where fuck knows what will happen
Definitely some interesting moves might happen within next 2 months
Why
Pretty normal and been done loads of times before i.e. Hiddink coaching PSV + Australia NT at the same time and that's coaching, not sitting there in boardroom meetings and having coffee at training
