Rotation is an issue the first few months of the seasons.
Why?
If you rotate the starting XI and the players position on the pitch all the time then it will take longer time for any new players to learn the system.
They will have learned it after a few months but then it may be to late.
If you play seven or eight players week in week out in the same positions and rotate the rest then the players will learn the system better.
Rafa didn't rotate some of his players in Valencia. Albelda, Baraja, Mista, Vicente, Ayala, Aimar and Marchena played more or less all the time.
