Think that has been the key to our run since we lost to West Ham. Rotating players does work because Chelsea, Arsenal and the Mancs have been doing it all season. However they very rarely change their systems, which means players coming in aren't coming into an unfamiliar formation. Under Rafa this season alone we've played 4-4-2, 3-4-1-2, 4-3-1-2, 4-3-3, 4-4-1-1, 4-1-4-1. Yes it is handy to have more than one system to play to depending on the opposition but that has been our problem! Our players just end up getting confused and cannot adapt to all of these different systems.
