So there is no way playing a different starting 11 week in week out effects the consistency of a team A.B, im not saying its the sole reason but its one of many.
You surely cant find 39 different team selections for 39 games healthy for the team, and i thought that injurys would limited the amount of players in the squad, leaving Rafa a smaller squad to pick from, and therefore needing to use the ame players more than ever.
