Okay I will bite. VVD, Gomez, Matip, Mane , Jota , Alisson are all out. Lets say for United we have Lindelof, Maguire, Bailly (Technically I could put Phil Jones here but I am being nice), Martial, Greenwood, De- Gea.
That Leaves a starting lineup of
Henderson (Europa league winner and world cup finalist Romero as cover)
Shaw, Tuanzebe, Mctominay (he plays defence for Scotland), AWB. (Brandon Williams as cover for the full backs and Telles could release Shaw into a left CB position if needed)
Midfield Poggers, Fernandes, Fred (Still have Matic, VDB and Mata to choose from)
Forward line of Rashford, Cavani, Daniel James (Potentially could be breakthrough for Diallo. Mata and VDB could also swap in for James playing a diamond or even Pogba on the left)
We would still be playing well with that line-up and have done as Ole has changed up to 8 players between games recently. Also if we were in Liverpool's situation we would have actually bought a premier league quality CB in January.
As for Chelsea they have an absolute monster of a squad. Just that Frank was a complete noob. Tuchel however should do a lot better.
