I prefer to give my new players a couple of sub appearances/friendlies to adjust, but it occurred to me this may be pointless.
Is there any evidence to support straight-in-the-team vs adjustment period?
From personal experience - putting them straight in the team seems to work well - don't really know if this is just for very good players, or if it would be even better the way you tend to do, or if it makes no difference.
