I didn't watch the second half, so I can't comment on that.
But when I have seen Bellingham play for England before, I always think he plays with an ego. He wants to always have the ball and be involved in everything and wants to be the one who makes things happen. I guess he seems to me as being more of an independent player, and when its working it's really effective, but it's all on him.
Rogers is more selfless and more of a team player, and if you get the right unit around him you see the best results, and it's less dependent on him being amazing on his own. That's why he works to well under Emery.
