Who really needs rest though? We've been out of the Champions League since March, out of the League Cup since last year and all we've had is the 120 minutes against City and plenty of rotation in between (primarily down to the change in formation).
I think it would be a shambles if we rest anyone in a game where we can still mathematically qualify for Europe and we are also still a whole week away from our FA Cup Final game which is to be played in London.. a not too unreasonable drive from where we usually play.
Basically, I agree with you. No need to ruin any sort of momentum we do have going.
