Like for like results, Ancelotti last season vs. Benitez now. I've swapped Norwich for the nearest equivalent (as Norwich won the Championship and Leeds are already involved, that is second placed WBA from 2019/20)
Benitez
Everton 3-1 Southampton
Leeds 2-2 Everton
Brighton 0-2 Everton
Everton 3-1 Burnley
Aston Villa 3-0 Everton
Everton 2-0 Norwich
TOTAL: 13 pts (+5 GD)
Ancelotti
Everton 1-0 Southampton
Leeds 1-2 Everton
Brighton 0-0 Everton
Everton 1-2 Burnley
Aston Villa 0-0 Everton
Everton 5-2 West Brom
TOTAL: 11 pts (+4 GD)
He's outperforming Ancelotti like for like.
