The only players who are 'restable' are Lascelles, Shelvey and Gayle, the others are rotated to the point where they'll never need resting. I wouldn't be too bothered about resting Lascelles, as it'll be Mbemba or Hanley making the step up, either are good enough against 90% of the league. We will miss Shelvey in any match against the other promotion contenders, but like Gayle we've got fringe players who bring something different to the team.
Not worried about 'resting' players in the slightest.
