Dropping Fred would be a big mistake. The huge hole in our midfield and on the edge of our box against Sheffield was a Fred-shaped one. Just because he's not our best player doesn't mean he's not an extremely important one.
If Pogba comes in, he comes in for McSauce. They're positionally similar. Anywhere else, you're shoe-horning him in, which is never a good idea. If we absolutely must swap him in for Greenwood again then fine, but only because that false RW position isn't currently hugely important to the way we play.
Personally I'd leave everything the same except Bailly in for Lindelof. Keep the momentum from S'oton by keeping the team as similar as possible.
