If we’re not going to use him in midfield then I’d have Davies at RB over Godfrey, his confidence will be shot after the weekend.
I also wouldn’t be surprised to see him start Sig on the left, although he’s not a like for like with Richarlison he does get close to DCL to support him and he’s keen to get a shot away like Richarlison is. I also think that you avoid the issues he has in the middle of the park if you stick him in the front three.
I’d prefer Gordon, but for whatever reason Ancelotti doesn’t seem keen to give him much time.
Tend to see Davies as more of a last 10 minutes kind of right back, play him there when we're out of subs kind of deal. Just not sure how he'd fare for a full 90 minutes. But, like you say, we don't want to hammer Godfrey's confidence 3 matches into his Everton career.
Agree about Gordon/Sig too - Sigurdsson's role should be on the bench, to replace Gomes/Richarlison/James depending on how the game is going. In Richarlison's absence, starting him over Gordon limits our penetration going forward - but given he seems to be the go-to captain in Coleman's absence, it would appear he'll be shoe-horned in somewhere.
