Would normally be a good idea mate, but it's who replaces him, Davies or Scneiderlin!
Lincoln would be the game too rest him.
I'd say if we are gonna rest him v Leicester, then the only way to do it is (probably in hindsight) what Silva should have done v Brighton - i.e. 3-4-3, with Gana and Gylfi in midfield.
That'd be the only way you could do it for me, other than - like you say - Davies or Schneiderlin coming in.
