No, you don't have a point.
He is a better talent than James, and yes we will keep James and send Amad on loan as they are not competing for the same position. No, James is not back up to Sancho, it is Greenwood and James won't play much on the right once all our players are available. Once again, this has little to do with James. He is not the reason for Amad to go on loan, it is Sancho and Greenwood who will play the majority of time.
And no, I am not saying that he is not ready for first team football, only that he has other players ahead of him so won't get much time if he stayed here, so better to go on loan. You are implying that he is not good enough for us as a player, and that James is his competition for RW, which is obviously not true.
And as explained already, the Tuanzebe and this are different situation, so no, you don't have a point.
