Yep, Fergy used to rotate UTD, but rarely changed the defence, he'd rotate MF & FW, but the defence was the same week in, week out. Title wining teams have a settled defense.
Also, defenders don't seem to burn out like MF & FW do, especially with Klopps style of play where MF & FW close down and cover allot of ground, so I can see why they rotate more, but it's not needed as much for the defenders.
Correct, but Klopp rotates his defenders and goalkeepers more than his midfielders and forwards. Again this makes absolutely no sense to me.
