I keep seeing this reference to James playing on the right of a 433
Ancelotti changed that because we couldn't cope with how much we were exposed defensively with James playing there. You won't be seeing that again under Benitez.
Secondly, the tactical pieces that Benitez has written in the Athletic and Times in the past, he talks about the importance of pace in attacking wide areas in modern football, particularly against top sides. As brilliant as he can be, James is one of the slowest attacking players we've had.
I suspect the only position you'll see him in would be as a number 10 and he won't be starting games other than the league cup unless there are injuries to contend with.
